Ligands: , , , Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum Function [C16MO_PSEPU] Involved in the degradation of (-)-camphor. Catalyzes the lactonization of the 3,6-diketocamphane via the Baeyer-Villiger oxidation to produce the unstable lactone (-)-5-oxo-1,2-campholide that presumably undergoes spontaneous hydrolysis to form 2-oxo-delta(3)-4,5,5-trimethylcyclopentenylacetic acid. It acts only on bicyclic ketones. Publication Abstract from PubMed The three-dimensional structures of the native enzyme and the FMN complex of the overexpressed form of the oxygenating component of the type II Baeyer-Villiger 3,6-diketocamphane monooxygenase have been determined to 1.9 A resolution. The structure of this dimeric FMN-dependent enzyme, which is encoded on the large CAM plasmid of Pseudomonas putida, has been solved by a combination of multiple anomalous dispersion from a bromine crystal soak and molecular replacement using a bacterial luciferase model. The orientation of the isoalloxazine ring of the FMN cofactor in the active site of this TIM-barrel fold enzyme differs significantly from that previously observed in enzymes of the bacterial luciferase-like superfamily. The Ala77 residue is in a cis conformation and forms a beta-bulge at the C-terminus of beta-strand 3, which is a feature observed in many proteins of this superfamily.
