'''THE INFLUENCE OF TEMPERATURE ON LYSOZYME CRYSTALS. STRUCTURE AND DYNAMICS OF PROTEIN AND WATER'''<br />


==Overview==
==Overview==
Lysozyme structures at six different temperatures in the range 95-295 K, have been determined using X-ray crystallography at a resolution of 1.7 A., The crystals at lower temperatures had a 7.4% decrease in the unit-cell, volume. The volume change was discontinuous with the volume being near 238, 000 A(3) from 295 to 250 K and about 220 200 A(3) below 180 K. The thermal, expansion of the protein has been analyzed and shows anisotropy, which is, correlated with local atomic packing and secondary-structure elements. The, lysozyme structure at low temperature is nearly the same as that at high, temperature, with only small relative translations and rotations of, structure elements including a hinge-bending rearrangement of two domains., Because of a considerable increase of lattice disorder at low temperature, dynamical analysis of internal motion is difficult. The analysis of, structural and dynamical properties of well ordered protein-bound water, has been carried out.
