Comparison of active site inhibitor S-methyl-L-cysteine sulfoxide (SMCS) Cys binding in V. cholerae (1MB4), P. aeruginosa (5BNT) and N. gonorrhoeae (6BAC) ASADH proteins. (A) Schematic of H-bond interactions between active site residues of V. cholerae (1MB4, blue) ASADH and SMCS, conserved in P. aeruginosa (5BNT, purple) and N. gonorrhoeae (6BAC, cyan) ASADH proteins. (B) SMCS (Cys, green) bound within the V. cholerae (3PZR) ASADH dimer. Important active site residues for H-bonding within the NADP binding site cavity are shown (yellow). (C) Active site residues responsible for SMCS binding through H-bond interactions in V. cholerae ASADH (1MB4, blue). Cys (green) represents the covalently bound inhibitor, SMCS, in V. cholerae ASADH (1MB4) through the formation of a disulfide bond. Important active site residues are conserved in P. aeruginosa (5BNT, purple) and N. gonorrhoeae (6BAC, cyan) ASADH proteins. (D) Superimposed structures of P. aeruginosa (5BNT, purple), N. gonorrhoeae (6BAC, cyan) and V. cholerae (1MB4, blue).
