Binding of activity modulators. (A) Binding of chloride in the active site. Note multiple hydrogen bonds between Cl and peptide amides. Yellow mesh represents anomalous difference electron density map contoured at 4 σ. Superposed L-proline (from the MtP5CR/L-proline complex, wires) is shown to visualize the Cl overlapping the carboxyl O. (B) Superposition of MtP5CR/L-proline and MtP5CR/NAD(P)+ complexes reveals that the MOPS molecule (originating from NAD(P)+ complexes) partially overlaps with L-proline (wires).
