Figure 6. The active site of Ni-MmARD showing the off-pathway product analog valeric acid (VA).

Figure 6

The Ni atom is shown as a green sphere. VA and active site residues are shown in stick representation. Waters are shown as small red spheres. The residues F84, F105, F135, A145, V143 and I98 which interact with the alkyl group of VA are shown in yellow. VA is within hydrogen bonding distance of R96 and with one of the two water molecules bound to Ni. The hydrogen bonding distances are shown as red dotted lines with distances measured in Å.
