Figure 2. Stereodiagram superposing present structure (yellow carbon) with the structure of hydroxy-inhibitor (JG365) complex(green) [PDB ID 2J9J]. The putative catalytic water H4 (orange sphere) is at 1.4 Å from the hydroxyl oxygen of the inhibitor. The flap water molecules (FW) for the two structures are also drawn.
