Figure 8.

Active site of glycine-soaked crystals of Y766F PlGoxA (PDB code 6VMF). A, omit F_o − F_c electron density contoured at 5.0σ for the active site modeled as CTQ. B, 2F_o − F_c electron density contoured at 1.0σ. C, overlay of the Y766F (cyan and yellow) and WT (gray) PlGoxA-active sites. Active-site residues shown as sticks are colored according to element. Carbons from residues of the neighboring protomer are colored yellow. Putative hydrogen bonds are shown as dotted lines with distances indicated in Å.
