-
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.
