Figure 4

Hydrogen bond interactions: A) the tetrahedral intermediate with PRWT; B) the two products with PRI47V mutant, and C) the single product with PRV32I mutant. Only the major conformation is shown for peptide intermediate or products in A) and B). Hydrogen bond interactions are indicated by dashed lines with distances in Å. Interactions of Asp25/25′ are omitted for clarity. PR is shown in gray carbons, TI and product peptides are in green. The water and carbonyl oxygen of Gly27′ in C) were refined with partial occupancy of 0.45.
