Triclinic lysozyme at 0.65 A resolution.
The crystal structure of triclinic hen egg-white lysozyme (HEWL) has been refined against diffraction data extending to 0.65 A resolution measured at 100 K using synchrotron radiation. Refinement with anisotropic displacement parameters and with the removal of stereochemical restraints for the well ordered parts of the structure converged with a conventional R factor of 8.39% and an R(free) of ...
متن کاملThe Shake-and-Bake structure determination of triclinic lysozyme.
The crystal structure of triclinic lysozyme, comprised of 1,001 non-H protein atoms and approximately 200 bound water molecules, has been determined ab initio (using native data alone) by the "Shake-and-Bake" method by using the computer program SnB. This is the largest structure determined so far by the SnB program. Initial experiments, using default SnB parameters derived from studies of smal...
متن کاملRefinement of triclinic hen egg-white lysozyme at atomic resolution.
X-ray diffraction data have been collected at both low (120 K) and room temperature from triclinic crystals of hen egg-white lysozyme to 0.925 and 0.950 A resolution, respectively, using synchrotron radiation. Data from one crystal were sufficient for the low-temperature study, whereas three crystals were required at room temperature. Refinement was carried out using the programs PROLSQ, ARP an...
متن کاملGenetic analysis of bacteriophage P22 lysozyme structure.
The suppression patterns of 11 phage P22 mutants bearing different amber mutations in the gene encoding lysozyme (19) were determined on six different amber suppressor strains. Of the 60 resulting single amino acid substitutions, 18 resulted in defects in lysozyme activity at 30 degrees; an additional seven were defective at 40 degrees. Revertants were isolated on the "missuppressing" hosts fol...
متن کاملRefolding of Lysozyme Upon Interaction with ?-Cyclodextrin
Effects of ?-cyclodextrin, ?CD, on refolding of lysozyme was investigated at pH 12 employing isothermal titration calorimetry (ITC) at 300K in 30mM Tris buffer solution. ?CD was employed as an anti-aggregation agent and the heats obtained for lysozyme+?CD interactions are reported and analyzed in terms of the extended solvation model. It was indicated that there are two sets of identical and no...
