MD simulations of the substrate sliding along the catalytic cleft of wild-type PG63 and its mutants.
Snapshots were taken at two different stages along the complete simulation. The GalpA6 was placed along the schematic binding groove with the catalytic residues at the subsite −1/+1 (top panel). The wild-type PG63 and its mutants had similar starting complex conformations that positioned along the −4 to +2 subsites. The simulations were performed twice for each enzyme.
