Dowser++, a new method of hydrating protein structures.

ABSTRACT: A new method of hydrating protein structures, which we call Dowser++, is presented. The method is based on a semi-empirical modification of a popular program for protein hydration Dowser, and the usage of protocols AutoDock Vina, and WaterDock. The positions of water molecules predicted by Dowser++ were compared with experimental data for a set of 14 high-resolution crystal structures of oligopeptide-binding protein (OppA) containing a large number of resolved internal water molecules, as well as for the D- and K-channels of cytochrome c oxidase, and the recent data on PSII. Comparison is also made with the predictions of the original Dowser, and its improved version, Dowser+, described in our previous publication. We also present a model for quantitative estimation of the quality of water
