Docking studies of nickel-peptide deformylase (PDF) inhibitors: exploring the new binding pockets.
The binding modes of a series of known activity inhibitors docking to Peptide deformylase (PDF) have been studied using molecular docking software AutoDock3.0.5. In this study, good correlation (R(2)=0.894) between calculated binding energies and experimental inhibitory activities is obtained. We find that some shallow pockets near the known active pocket are very important which can accommodate the side-chains of the inhibitor. Moreover, a new binding pocket is also explored. All these may provide something useful for designing the potent inhibitors.
