    Collagen and Elastin in Different Cuts of Veal and Beef (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 33 (1968), S. 0

    Notes: SUMMARY– The collagen and elastin content was determined in different cuts of veal and beef. Increases in the amount of total connective tissue are primarily due to increased amounts of collagen, whereas the elastin content is relatively constant. More collagen was found in veal than in beef. The amount of collagen solubilized by heating in one-fourth strength Ringer's solution was twice as high for veal as for beef. Results indicate that the amount of connective tissue proteins in meat is dependent upon the anatomical location and the physiological function of the muscles. Results of chemical and histological analysis are discussed from the standpoint of their nutritional significance.

    Notes: An 8kb segment of DNA from the 58/59 min region of the E. coli chromosome, which complements the defect of a mutant devoid of hydrogenase 3 activity, has been sequenced. Eight open reading frames were identified which are arranged in a transcriptional unit; all open reading frames were transcribed and translated in vivo in a T7 promoter/polymerase system. Analysis of the amino acid sequences derived from the nucleic acid sequences revealed that one of them, open reading frame 5 (0RF5), exhibits significant sequence similarity to conserved regions of the large subunit from Ni/Fe hydrogenases. Two of the open reading frames (orf2, orf6) code for proteins apparently carrying iron-sulphur clusters of the 4Fe/4S ferredoxin type. The product of one of the open reading frames, orf7, displays extensive sequence similarity with protein G from the chloroplast electron transport chain. ORF3 and ORF4, on the other hand, are extremely hydrophobic proteins with nine and six putative transmembrane helices, respectively. Over a limited hydrophilic sequence stretch, bordered by putative transmembrane areas, ORF3 and ORF4 exhibit homology with subunits 4 and 1 of mitochondrial and plastid NADH-ubiquinol oxidoreductases, respectively. The operon described, therefore, appears to comprise genes for redox carriers linking formate oxidation to proton reduction and for a hydrogenase of hitherto unique composition.

    Molecular characterization of an operon (hyp) necessary for the activity of the three hydrogenase isoenzymes in Escherichia coli (1991)

    Notes: The 58/59 min region of the Escherichia coli chromosome contains two divergently oriented gene clusters coding for proteins with a function in hydrogenase formation. One cluster (the hyc operon), transcribed counterclockwise with respect to the E. coli chromosome, codes for gene products with a structural role in hydrogenase 3 formation (Böhm et al., 1990). The nucleotide sequence of the divergently transcribed operon (hyp) has been determined. It contains five genes, all of which are expressed in vivo in a T7 promoter/polymerase system, and the sizes of the synthesized products correspond with those predicted from the amino acid sequence. Complementation analysis of previously characterized mutants showed that the hypB, hypC and hypD genes have a function in the formation of all three hydrogenase isoenzymes, lesions in hypB being complemented by high nickel ion concentration in the medium. Prevention of hypBCDE gene expression led to an altered electrophoretic pattern of hydrogense 1 and 2 constituent subunits, indicating increased chemical or proteolytic susceptibility. Under fermentative growth conditions, operon expression was governed by an NtrA-dependent promoter lying upstream of hypA working together with an fnr gene product-dependent promoter which was localized within the hyp A gene. The latter (operon-internal) promoter is responsible for hypBCDE transcription under non-fermentative conditions when the -24/-12 NtrA-dependent promoter upstream of hyp A is silent.

    Characterization of divergent NtrA-dependent promoters in the anaerobically expressed gene cluster coding for hydrogenase 3 components of Escherichia coli (1990)

    Notes: The regulatory region of two divergently oriented transcriptional units involved in the formation of the gas-evolving hydrogenase (isoenzyme 3) of Escherichia coli was investigated. DNA sequence analysis revealed the existence of a 210bp non-coding region containing two sequences showing homology to -24/-12 NtrA-dependent promoters. These sequences were arranged in a divergent orientation entirety consistent with their being involved in transcribing the divergent operons. Through S1 protection experiments it could be shown that transcription of both promoters was NtrA-dependent and that it was regulated in an identical manner: oxygen repressed expression, as did anaerobic growth in the presence of nitrate; transcription was induced in cells grown anaerobically in the absence of exogenous electron acceptors and formate was found to be obligately required for this anaerobic induction. Lying at an approximately equal distance between both promoters was a short stretch of DNA which showed similarity to the sequence previously identified (Birkmann and Böck, 1989a) as being necessary for formate induction of the fdhF gene.

    Mutational analysis of the operon (hyc) determining hydrogenase 3 formation in Escherichia coli (1992)

    Notes: In-frame deletions were introduced into each of the eight genes of the hyc operon coding for products required for the formation of the formate hydrogenlyase (FHL) system. The deletions were transferred to the chromosome and the resulting mutants were analysed for development of formate dehydrogenase H and hydrogenase 1, 2 and 3 activity. It was found that hycA, the promoter-proximal gene, is a regulatory gene and that it codes for a product counteracting transcriptional activation by FhlA. Deletions within the hycB to hycH genes specifically affected formate dehydrogenase H activity or hydrogenase 3 activity, or both. None of the mutations affected hydrogenase 1 or 2 activity. A model is proposed for the functional interaction of the different hyc operon gene products in the formate hydrogenlyase complex, which is based on the results of the mutational analysis, on the determination of the subcellular localization of the FdhF, HycE, HycF and HycG polypeptides and on the similarity of hyc gene product sequences with those from other hydrogenase systems. HycH, the product of the most promoter-distal gene, does not seem to form part of the functional FHL complex but rather is required for the conversion of a precursor form of the large subunit of hydrogenase 3 into the mature form.

    Notes: Abstract. The polarization transfer from longitudinally polarized electrons to protons in the elastic scattering p( e, e' p) has been measured around Q2 = 0.4 (GeV/c)2 with the three-spectrometer facility at the Mainz microtron MAMI. From this polarization transfer the ratio G Ep/(G Mp/μp) has been determined. The ratio is found to be slightly less than unity in agreement with recent results from other laboratories and from the Rosenbluth separation of cross-sections measured with unpolarized electrons.

    Notes: Abstract: The reaction 12C(e,e'Δ0)11C →12C(e,e'pπ−)11C was investigated at the Mainz Microtron MAMI in a triple coincidence measurement using the three spectrometer setup of the A1 Collaboration. The good missing mass resolution of σm= 0.27 MeV/c2 allowed to select the events belonging to the ground state of 11C. Cutting on these events the excitation energy spectra of 12CΔ0 show evidence for two peaks of about 4 MeV width (FWHM) at 282 MeV and 296 MeV with a significance of about 4.5 standard deviations. The peaks are interpreted in a simple weak coupling model as bound Δ0 states in 12CΔ0.

    Notes: Abstract The perturbed angular correlation of the 173 keV—247 keVγ-γ-cascade in111Cd was measured for proton-irradiated and quenched cadmium as a function of the annealing temperature. Three distinct defect configurations were identified by the quadrupole interaction frequencies:D 1 with $$\left| {v_Q } \right| = \left| {\frac{{eQV_{zz} }}{h}} \right| = 103\left( 3 \right)$$ MHz visible for annealing temperaturesT A between 110 K and 130 K,D 2 with |v Q | between 4 and 22 MHz observed for 110 K ≦T A ≦150 K, andD 3 with no electric field gradient. The fractionD 3 is seen from 77 K to room temperature. The defect configurationsD 1 andD 2 are of vacancy type. It is argued thatD 1 originates from simple defect structures (probably mono- or divacancies) whileD 2 is attributed to small vacancy agglomerates. Because of its larger stability,D 3 is ascribed to defect loops. The experiment shows clearly that a vacancy-like defect is mobile in recovery stage III in Cd.
