AMICYANIN OXIDIZED, 1.31 ANGSTROMS
Overview
High-resolution X-ray diffraction data to d(min) = 1.31 A were collected on a Xuong-Hamlin area detector from crystals of the blue-copper protein amicyanin, isolated from P. denitrificans. With coordinates from the earlier 2.0 A structure determination as a starting point, simulated annealing and restrained positional and temperature factor refinements using the program X-PLOR resulted in a final R factor of 15.5%, based on 21 131 unique reflections in the range 8.0-1.3 A. Comparison of the 1.31 A structure with that at 2.0 A shows the same basic features. However, the high-resolution electron-density maps clearly reveal additional solvent molecules and significant discrete disorder in protein side chains and within the solvent structure. As a consequence of modelling side-chain disorder, several new hydrogen-bonding interactions were identified.
