Fig. 1. (a) Model of Ht-CoM61A based on PDB ID: ; 1AYG. To prepare this structure, the distal heme ligand was mutated (M61A) using PYMOL to show the open coordination site for interaction with substrate. (b) CoMC6*a model (ref. 26). The peptide backbones are represented as ribbons, the decapeptide (D) chain in teal, and the tetradeceapeptide (TD) chain in pink. Selected labeled residues are represented as sticks. The amino acid sequence of the D chain is Ac-D-E2-U3-Q-L-S6-U7-Q-K-R10–NH2 and the TD chain is Ac-D-L2-Q-Q-L-H6-S-Q-K-R10-K-I-T-L–NH2. (c) Drawing of CoMP11-Ac.
