Common Hydrogen Bond Interactions in Diverse Phosphoryl Transfer Active Sites
Figure 3
Mean number of enzyme-ligand interactions.
Interactions are shown with nonbridging β- (A), bridging β- (B) and bridging α-oxygens (C) in the O3β―Pγ cleaving-, Pα―O3α cleaving- and non-catalytic-NTP-binding sites. The resolution cutoff of structures used is 2.7 Å, and water is not included. Bars show standard errors.
