Binding dynamics of two water molecules constrained within the scytalone dehydratase binding pocket.
Two water molecules reside between inhibitors and active site residues of scytalone dehydratase. A molecular dynamics study is consistent with one water molecule binding less tightly than the other. Inhibitor binding studies with site-directed mutants indicate that the hydrogen bonding network around the less mobile water molecule contributes much greater binding energy than that around the more mobile one.
