- Provar analysis of a tCONCOORD generated ensemble of 250 structures of the apo form of each of the 11 proteins in the 2P2I database identifies a greater proportion of the known binding site atoms as pocket-lining than analysis of the crystallographic structure alone. The proportion of inhibitor binding-site atoms found to be persistently or variably lining pockets (defined as pocket-lining in at least 25% of conformers) is significantly greater than for the protein as a whole in 21/33cases. (An italic number in the final column indicates the minority of cases in which the proportion is not significant at the p < 0.05 level). Further details of the structures are given in Table 4.
