摘要
An empirical relationship between occupancy and the atomic displacement parameter of water molecules in protein crystal structures has been found by comparing a set of cr ell refined sperm whale myoglobin crystal structures. The relationship agrees with a series of independent structural features whose impact on water occupancy can easily be predicted as well as with other known data and is independent of the protein fold. The estimation of the water occupancy in protein crystal structures mag help in understanding the physico-chemical properties of the protein-solvent interface and call allow the monitoring of the accuracy of the protein crystal structure refinement.
