    Notes: Summary Evaporation of a solution of thymidine plus either theexo or theendo diastereomer of uridine cyclic 2′,3′-O, O-phosphorothioate (U 〉 p(S) in 1,2-diaminoethane hydrochloride buffer gave the 2′,5′ and 3′,5′ isomers of (P-thio) uridylylthymidine (Up(S)dT) in a ratio of 1:2 with a combined yield of about 20%. These isomers were re-converted to U 〉 p(S) and dT by a reaction that is known to proceed by an in-line mechanism. Both the 2′,5′ and 3′,5′ isomers gave as product the same diastereomer of U 〉 p(S) that had been used originally in their formation. These dry-state ‘prebiotic’ reactions (Verlander, Lohrmann, and Orgel 1973) are thus shown to be stereospecific, and both the 2′,5′ and 3′,5′ internucleotide bonds are formed by an in-line mechanism.

    Amino acid sequence homology between histone H5 and murine leukemia virus phosphoprotein p12 (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-03-30
    Description: The amino terminal acid sequences of several mouse leukemia virus phosphoproteins (p12) show definite homology with the amino terminal conserved region of H5 histones, the phosphorylated nuclear proteins of nucleated erythrocytes. Differences in the amino acid compositions of the two groups of proteins seem to rule out the possibility that they evolved from a single common ancestral gene. The finding of sequence homology between viral p12's and cellular histones, however, is consistent with evolution of retrovirus structural proteins by a process of differentiation from preexisting cellular genes. The conserved primary and secondary structure at the amino terminal region, common to both groups of proteins, may be related to their common function of nucleic acid binding modulated by phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Henderson, L E -- Gilden, R V -- Oroszlan, S -- New York, N.Y. -- Science. 1979 Mar 30;203(4387):1346-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/218289" target="_blank"〉PubMed〈/a〉

    Specific nonopiate receptors for beta-endorphin (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-07
    Description: Iodinated beta H-[2-D-alanine]endorphin exhibits specific binding to cultured human lymphocytes. The binding is inhibited by low concentrations of beta-endorphin and its D-alanine derivative, but is not affected by opiate agonists and antagonists, or by enkephalin analogs, beta-lipotropin, adrenocorticotrophic hormone, or alpha-melanocyte-stimulating hormone; this suggests the existence of a specific, non-opiate binding site (receptor) for beta-endorphin. The carboxy-terminal region of beta-endorphin is essential for this binding activity, since alpha-endorphin is not active. beta-Endorphin may be a circulating hormone with peripheral physiological effects that are not primarily mediated through interactions with opiate or enkephalin receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hazum, E -- Chang, K J -- Cuatrecasas, P -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1033-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224457" target="_blank"〉PubMed〈/a〉

    Chicken gizzard: relation between calcium-activated phosphorylation and contraction (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-05-04
    Description: Of the proteins in mechanically disrupted chicken gizzard fibers (no functional sarcolemma) only the 20,000-dalton light chains of myosin underwent large Ca2+-and Sr2+-dependent changes in phosphorylation. Phosphorylation closely corresponded with the Ca2+- and Sr2+-activated tensions. Adenosine 5'-O (3'-thiotriphosphate) only in the presence of Ca2+ induced irreversible Ca2+-insensitive activation of tension and thiophosphorylation of the 20,000-dalton light chains, and blocked incorporation of 32P from [gamma-32P]adenosine triphosphate into the myosin light chains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hoar, P E -- Kerrick, W G -- Cassidy, P S -- New York, N.Y. -- Science. 1979 May 4;204(4392):503-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/432654" target="_blank"〉PubMed〈/a〉

    Fibrinopeptide B and aggregation of fibrinogen (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-04-13
    Description: Removal of fibrinopeptide B from human fibrinogen by reaction with the procoagulant enzyme from copperhead snake venom below 25 degrees C resulted in tight aggregation of the fibrinogen, which, in turn, progressively blocked a concomitant but sluggish release of fibrinopeptide A by the enzyme. When the clots obtained at less than 25 degrees C were warmed, they dissociated into soluble aggregates and monomers. Release of fibrinopeptide A then resumed, and a secondary coagulation followed. The aggregation induced by release of fibrinopeptide B itself involves a plasmin-susceptible segment located just distal to B in the B beta chain of fibrinogen, a segment previously shown to be of little importance in the aggregation induced by release of fibrinopeptide A.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shainoff, J R -- Dardik, B N -- New York, N.Y. -- Science. 1979 Apr 13;204(4389):200-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/155308" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-03-09
    Description: Three hypotheses to explain the amino acid composition of proteins are inconsistent (P congruent to 10(-9) with the experimental data for beta-galactosidase from Escherichia coli. The exceptional length of this protein, 1021 residues, permits rigorous tests of these hypotheses without complication from statistical artifacts. Either this protein is not at compositional equilibrium, which is unlikely from knowledge about other proteins, or the evolution of this protein and its coding gene have not been selectively neutral. However, the composition of approximately 60 percent of the molecule is consistent with either a selectively neutral or nonneutral evolutionary process.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holmquist, R -- New York, N.Y. -- Science. 1979 Mar 9;203(4384):1012-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/106468" target="_blank"〉PubMed〈/a〉

    Description: The I region of the major histocompatibility complex contains immune response genes that display considerable polymorphism; that is, there are many alleles at each locus. These genes regulate the immune response to antigen by mediating intercellular communication among lymphoreticular cells. An analysis of the primary structure of the products of two subregions of (I-A, I-E/C) was undertaken in order to understand the genetic organization of the region, the evolution of the genes and, eventually, their function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Uhr, J W -- Capra, J D -- Vitetta, E S -- Cook, R G -- New York, N.Y. -- Science. 1979 Oct 19;206(4416):292-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/113876" target="_blank"〉PubMed〈/a〉

    Cyclic AMP receptor triggers nuclear protein phosphorylation in a hormone-dependent mammary tumor cell-free system (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-28
    Description: Adenosine 3',5'-monophosphate (cyclic AMP) receptor protein of 56,000 daltons increases markedly in mammary tumors induced by 7,12-dimethylbenz[a]anthracene (DMBA) after incubation of tumor slices with cyclic AMP, benzamide, and arginine. Incubation of cytosol from these tumor slices with nuclei from unincubated tumors results in nuclear uptake of the 56,000-dalton cyclic AMP receptor and in phosphorylation of the 76,000-dalton nuclear protein. Binding of the 56,000-dalton receptor and phosphorylation of the 76,000-dalton protein also occur in DMBA tumor nuclei when protein kinase type II of bovine heart is used. The results suggest that cyclic AMP receptor is involved in the nuclear events of a hormone-dependent mammary tumor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho-Chung, Y S -- Archibald, D -- Clair, T -- New York, N.Y. -- Science. 1979 Sep 28;205(4413):1390-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224463" target="_blank"〉PubMed〈/a〉

    A synthetic pentapeptide with biological activity characteristic of the thymic hormone thymopoietin (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-06-22
    Description: The pentapeptide arginyl-lysyl-aspartyl-valyl-tyrosine, corresponding to amino acid residues 32--36 in thymopoietin, was synthesized. In vitro, this pentapeptide induced the differentiation of murine prothymocytes to thymocytes and inhibited differentiative induction of cells of the B lineage. This combination of actions is presently unique to the parent molecule thymopoietin. In vivo, the pentapeptide reduced the high numbers of autologous rosette-forming cells normally present in the spleens of athymic mice; this also is a property of thymopoietin. These results suggest that this readily synthesized pentapeptide corresponds to an active site of thymopoietin and might serve as a therapeutic substitute for thymopoietin.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldstein, G -- Scheid, M P -- Boyse, E A -- Schlesinger, D H -- Van Wauwe, J -- New York, N.Y. -- Science. 1979 Jun 22;204(4399):1309-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451537" target="_blank"〉PubMed〈/a〉

    Local cerebral glucose metabolism during controlled hypoxemia in rats (1979)

    Publication Date: 1979-05-11
    Description: 2-Deoxy-[14C]glucose metabolism was examined in brains of hypoxic, normotensive rats by autoradiography, which revealed alternating cortical columns of high and low metabolism. Activity in white matter was increased severalfold over that in adjacent gray matter. The columns were anatomically related to penetrating cortical arteries with areas between arteries demonstrating higher rates of metabolism. The results suggest the presence of interarterial tissue oxygen gradients that influence regional glucose metabolism. The relatively greater sensitivity of white matter metabolism to hypoxia may lead to an understanding of white matter damage in postanoxic leukoencephalopathy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pulsinelli, W A -- Duffy, T E -- New York, N.Y. -- Science. 1979 May 11;204(4393):626-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/432667" target="_blank"〉PubMed〈/a〉

    Synaptic phosphoproteins: specific changes after repetitive stimulation of the hippocampal slice (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-01-05
    Description: Repetitive stimulation (100 pulses per second for 1 second) of the Schafer collateral-commissural system of the rat hippocampus induces long-term potentiation of synaptic strength and produces significant changes in the subsequent endogenous phosphorylation of a 40,000-dalton protein from synaptic plasma membranes. This effect is not observed after stimulation in calcium-deficient media or after simulation at the rate of one pulse per second for 100 seconds. These findings provide evidence that repetitive synaptic activation can alter the phosphorylation machinery of the synaptic region and suggest a biochemical process which may be involved in the production of neuronal plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Browning, M -- Dunwiddie, T -- Bennett, W -- Gispen, W -- Lynch, G -- New York, N.Y. -- Science. 1979 Jan 5;203(4375):60-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/214855" target="_blank"〉PubMed〈/a〉

    Description: The bis-acridine ring system forms the basis for new biophysical probes of novel stereochemistry. Spectral data indicate that certain alkylene bridged bis-9-aminoacridines have a parallel plane conformation of predictable interplane distance.

    Publication Date: 1979-02-09
    Description: Like physicists striving to develop a unified field theory, immunologists are attempting to bring order to the microcosmos of defense reactions. Indications are that one of the most important constants in this microcosmos is the major histocompatibility complex (MHC) of the species. A test of any interpretation of the MHC's role in immunity is how well it explains this system's polymorphism. One of the most crucial questions an MHC hypothesis must answer is: Why are there so many alleles at this complex?〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klein, J -- New York, N.Y. -- Science. 1979 Feb 9;203(4380):516-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/104386" target="_blank"〉PubMed〈/a〉

    Human growth hormone: complementary DNA cloning and expression in bacteria (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-10
    Description: The nucleotide sequence of a DNA complementary to human growth hormone messenger RNA was cloned; it contains 29 nucleotides in its 5' untranslated region, the 651 nucleotides coding for the prehormone, and the entire 3' untranslated region (108 nucleotides). The data reported predict the previously unknown sequence of the signal peptide of human growth hormone and, by comparison with the previously determined sequences of rat growth hormone and human chorionic somatomammotropin, strengthens the hypothesis that these genes evolved by gene duplication from a common ancestral sequence. The human growth hormone gene sequences have been linked in phase to a fragment of the trp D gene of Escherichia coli in a plasmid vehicle, and a fusion protein is synthesized at high level (approximately 3 percent of bacterial protein) under the control of the regulatory region of the trp operon. This fusion protein (70 percent of whose amino acids are coded for by the human growth hormone gene) reacts specifically with antibodies to human growth hormone and is stable in E. coli.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Martial, J A -- Hallewell, R A -- Baxter, J D -- Goodman, H M -- New York, N.Y. -- Science. 1979 Aug 10;205(4406):602-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/377496" target="_blank"〉PubMed〈/a〉

    alpha1-Antitrypsin: the presence of excess mannose in the Z variant isolated from liver (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-09-29
    Description: The Z variant of alpha1-antitrypsin was isolated by a new technique from the liver of a patient homozygous for the Z allele of the protease inhibitor locus. The material was homogenous and antigenically competent but had no protease inhibiting capacity. An interesting correlation was found between the subcellular localization and the carbohydrate composition of the Z variant from liver. Carbohydate analysis of this glycoprotein showed an absence of galactose and sialic acid, an appreciable decrease in N-acetylglucosamine, and an almost twofold increase in mannose residues. These data indicate a considerable slowdown in the processing of the oligosaccharides of liver Z variant. In spite of the absence of sialyl residues, the liver Z varant was microheterogeneous by analytical isoelectric focusing. The isoproteins of liver Z variant coincided with those of asialo M variant in the focusing field.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hercz, A -- Katona, E -- Cutz, E -- Wilson, J R -- Barton, M -- New York, N.Y. -- Science. 1978 Sep 29;201(4362):1229-32.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/308696" target="_blank"〉PubMed〈/a〉

    Description: The collagens of all major invertebrate phyla have been studied, but characterization has been thorough in only a few classes and in no case in the detail (such as sequence analysis) known for vertebrate collagen. Biochemical data on insect collagen are particularly sparse. Invertebrate and vertebrate collagens are strikingly similar, with some notably unique features in annelids and nematodes. Present data do not support the suggestion that invertebrate collagens resemble vertebrate basement membrane collagen. In invertebrates, as in vertebrates, collagens of specific tissues show differenes that probably reflect individual tissue requirements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adams, E -- New York, N.Y. -- Science. 1978 Nov 10;202(4368):591-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/212833" target="_blank"〉PubMed〈/a〉

    Electrostatic effects in proteins (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-09-29
    Description: Electrostatic effects dominate many aspects of protein behavior. When polypeptide chains fold up, most polar side chains seek the exterior, where they can be solvated. Water bound in the interior has been found between the domains of enzymes of the chymotrypsin family, and between the subunits of hemoglobin and tobacco mosaic virus protein. Assembly of this protein from disk to virus is triggered by electrostatic interactions between neighboring subunits. Lysozyme stabilizes the constellation of charges involved in the transition state of its substrate by both permanent and induced dipoles. All factors that lower the oxygen affinity of hemoglobin act by strengthening the salt bridges that constrain its quaternary deoxy (T) structure. Enzymes of thermophile bacteria owe their extra stability mostly to additional salt bridges. The rate of denaturation of hemoglobins by alkali is determined by the ionization of internal side chains with pK's of about 12.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perutz, M F -- New York, N.Y. -- Science. 1978 Sep 29;201(4362):1187-91.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/694508" target="_blank"〉PubMed〈/a〉

    Vasopressin analog with extraordinarily high antidiuretic potency: a study of conformation and activity (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-01-20
    Description: Application of information derived from a three-dimensional model of vasopressin bound to its antidiuretic receptor has resulted in the design and synthesis of a potent analog, [1-deamino, 2-phenylalanine, 7-(3,4-dehydroproline)]-arginine vasopressin; this analog has a specific antidiuretic activity of 13,000 +/- 1,250 units per milligram; noteworthy at these doses is the absence of any detectable pressor activity. Three modifications based on conformational considerations were introduced into the vasopressin molecule in preparing the analog: (i) to enhance binding, a double bond was introduced into the side chain of an amino acid residue occupying a corner position of a beta turn in the vasopressin conformation, (ii) the hydroxyl moiety was deleted from Tyr2, and (iii) to tighten the backbone structure and to enhance the enzymatic resistance of the analog, the NH2-terminal amino group was deleted.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, C W -- Walter, R -- New York, N.Y. -- Science. 1978 Jan 20;199(4326):297-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/619455" target="_blank"〉PubMed〈/a〉

    Notes: Abstract Light-induced phosphorylation of rhodopsin has been extensively studied by a number of investigators from a biochemical point of view. However, little is known about the physiological function of this reaction. The slow rates measured for phosphorylation and dephosphorylation suggest that it may be involved in visual adaptation rather than in excitation. This paper presents biochemical data obtained from phosphorylation experiments in isolated photoreceptor membranes as well as in the more physiological system of whole retinas and living animals. An attempt is made to compare the phosphorylation reaction with visual adaptation hypotheses taken from the electrophysiological literature. Finally, effects of cyclic nucleotide metabolism on the sensitivity of photoreceptors are presented and discussed.

    Notes: Abstract 32P-rhodopsin was partially separated by isoelectric focusing into several fractions of different phosphorylation extent. It was found that the incorporated phosphate is not uniformly distributed in a population of rhodopsin molecules. In a preparation with an average phosphorylation extent of 2.4 moles of phosphate per mole of rhodopsin, most of the 32P-phosphate was found in fractions where 4–5 phosphates are bound per rhodopsin, whereas a large fraction of the total rhodopsin was not phosphorylated at all. The maximum number of phosphate binding sites in rhodopsin appears to be at least five.

    Notes: Abstract The influence of light and different concentrations of ATP on cell aggregation in cyclic AMP sensitive (Dictyostelium mucoroides, D. purpureum) and cyclic AMP insensitive species (Polysphondylium violaceum, P. pallidum, D. lacteum) of the cellular slime molds was observed in small and in large amoebal populations. Both light and ATP (optimal concentration:10-5M) accelerated cell aggregation and increased the number of aggregating centers in large populations. For cyclic AMP sensitive species the effect of ATP in large populations was more pronounced than for the species that do not react to cyclic AMP. A possible explanation for the similar effect of light and ATP has been discussed.
