    Genome analysis and the human X chromosome (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-10-02
    Description: A unified genetic, physical, and functional map of the human X chromosome is being built through a concerted, international effort. About 40 percent of the 160 million base pairs of the X chromosome DNA have been cloned in overlapping, ordered contigs derived from yeast artificial chromosomes. This rapid progress toward a physical map is accelerating the identification of inherited disease genes, 26 of which are already cloned and more than 50 others regionally localized by linkage analysis. This article summarizes the mapping strategies now used and the impact of genome research on the understanding of X chromosome inactivation and X-linked diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mandel, J L -- Monaco, A P -- Nelson, D L -- Schlessinger, D -- Willard, H -- New York, N.Y. -- Science. 1992 Oct 2;258(5079):103-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire de Genetique Moleculaire des Eucaryotes du CNRS, INSERM, Strasbourg, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1439756" target="_blank"〉PubMed〈/a〉

    Differentiation between the α-helical and coillike conformations of poly(L-glutamic acid) in aqueous solution through binding of pinacyanol (1979)
    New York : Wiley-Blackwell

    Notes: Pinacyanol in the presence of an excess of poly(L-glutamic acid) [polymer/dye ratio (P/D) 〉 10] exhibits different absorption spectra in the visible region when bound to the slightly charged polypeptide in the α-helical conformation or to the nearly completely dissociated polypeptide in the coillike conformation. These spectra reveal aggregation of the dye bound to the macromolecular chain in both conformations, although in the coillike one different kinds of aggregates may be present. Dye binding is accompanied by the appearance of CD bands in the visible region which are also different for the α-helical and the coillike conformations. The aggregates formed in the presence of the latter change slowly in time and seem to induce some conformational changes in the polypeptide chain. Furthermore, they have been found to be, at least partially, stable with respect to a subsequent reversal to the α-helical conformation. All results could be qualitatively interpreted assuming that in the coillike conformation, ordered regions exist along the chain as proposed by Krimm and Tiffany.

    Notes: A series of copolymers of L-lysine and L-valine [poly(L-lysinef L-valine100-f)] containing 0-13% L-valine have been studied, in 0.10M KF solution, using potentiometric titration and circular dichroism spectroscopy. Incorporation of increasing amounts of valine into the copolymers favors β-sheet formation over α-helix formation at high pH and room temperature. The titrations were analyzed using the method of Zimm and Rice and the partial free energy (ΔG0cβ) for the coil-to-β-sheet transition for valine is estimated at 900 cal/mole at 25°C. From the temperature dependence of the free energy, the partial enthalpy, ΔH0cβ, and entropy, ΔS0cβ, of the transition for valine is estimated to be 854 cal/mole and 6.0 e.u., respectively. The corresponding partial thermodynamic parameters for L-lysine are in agreement with published results. The fraction of β-sheet versus pH has been calculated for poly(L-lysine86.8 L-valine13.2) at 25.0°C using the titration data; data obtained from circular dichroism spectroscopy for the same copolymer are in good accord. It is concluded from these results that L-valine is a very strong β-sheet forming amino acid. Furthermore, these results indicate that the Zimm-Rice method is applicable to transitions between the coil and β-sheet states for a polypeptide containing two different residues.

    Circular dichroism of the complex between N-N′-diethylpseudoisocyanine and sodium poly(L-glutamate) in aqueous solutions (1977)
    New York : Wiley-Blackwell
    Biopolymers 16 (1977), S. 33-41 
    Details
    ISSN: 0006-3525

    Topics: Chemistry and Pharmacology
    Notes: In the presence of sodium poly(L-glutamate) at pH = 7.5 the dye pseudoisocyanine in dilute aqueous solution (Cd = 1.10 × 10-5 M) and low P/D values exhibits an absorption spectrum with a very sharp red-shifted J-band. Under the same conditions circular dichroism (CD) in the visible region is observed with an extremely sharp peak at the position of the J-band. At pH = 4.6, where the polypeptide is in the α-helix conformation, no such J-band is observed and no CD spectrum can be detected at the same P/D values. CD spectra in the uv range demonstrate that the occurrence of the dye-polypeptide complex which gives rise to the J-band at slightly alkaline pH is not accompanied by a conformational transition of the polypeptide towards the α-helical form.

    A hydrodynamic study with quasielastic light scattering and sedimentation of bacterial elongation factor EF-Tu · guanosine-5′-diphosphate complex under nonassociating conditions (1990)

    Notes: The hydrodynamics of the bacterial elongation factor EF-Tu have been studied in the presence of its ligand guanosine-5′-diphosphate (GDP) by sedimentation in the ultracentrifuge and quasielastic light scattering. Sedimentation studies have made it possible to establish experimental conditions under which only negligible aggregation of the protein occurs (neutral pH, concentration 〈 3 mg/mL). Analysis of the light intensity autocorrelation functions under these conditions revealed two independent scattering species with diffusion coefficients of 0.71 × 10-6 and 0.04 × 10-6 cm2 s-1. The material with the lower diffusion coefficient, i.e., the aggregates, represented less than 1% of the total number of EF-Tu particles. The other 99% diffused as monomeric molecules with a molar mass corresponding to the value calculated from the known primary structure of the protein. The hydrodynamic parameters derived from the experimental data suggest that EF-Tu·GDP in solution is close to a spherical particle.

    Physicochemical properties of aqueous xanthan solutions: Static light scattering (1994)
    New York : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: The secondary structure of xanthan in solutions of relatively low salt concentration and at room temperature has been investigated using static light scattering experiments. Additional evidence has been found for a dimeric structure at 25°C in 0.01M NaCl. From the experimental z-average mean square (ms) radius of gyration, a value for the persistence length p has been estimated, taking explicitly into account the polydispersity of the three samples used, which has been established by gel permeation chromatography (GPC) measurements. The experimental particle scattering functions of the three samples are consistent with theoretical estimates for polydisperse systems with the same value of p = 65 ± 10 nm and the molar mass per unit length for a dimeric structure.This secondary structure remains unaffected by the ionic strength in the 0.005-0.0lM range. Partial aggregation seems to occur at higher NaCl concentrations.Light scattering and GPC data show that heating the xanthan 0.01M NaCl solutions to about 70°C considerably reduces the Mw of the low molar mass sample (2.3 × 105-g·mol-1), contrary to what is observed for the high molar mass sample (1.8 × 106-g·mol-1). These experimental findings can be accounted for by a partial temperature-induced dissociation of the xanthan dimers according to an all-or-none mechanism. © 1994 John Wiley & Sons, Inc.

    Dielectric properties of maleic acid-ethylene copolymer in salt-free aqueous solutions (1978)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Physics Edition 16 (1978), S. 641-651

    Topics: Chemistry and Pharmacology , Physics
    Notes: The dielectric behavior of maleic acid-ethylene copolymer solutions has been investigated at different polymer concentrations and two degrees of neutralization α′. It is shown that this behavior is analogous to that of ordinary polyacids. Also the experimental data can be explained in terms of the van der Touw-Mandel theory, but at low α′ a possible contribution from motion of negative charges (in turn related to bound proton fluctuations) has to be taken into account. The dielectric results suggest that the formation of intramolecular hydrogen bonds has an influence on the change of the average dimensions of the chain with increasing α′. This seems to be confirmed by viscosity data.
