Function

36DKM_PSEPU Involved in the degradation and assimilation of (-)-camphor, which allows P.putida strain NCIMB 10007 to grow on this enantiomer of camphor as the sole carbon source (PubMed:8515237). Catalyzes the FMNH(2)-dependent lactonization of 3,6-diketocamphane via a Baeyer-Villiger oxidation to produce the unstable lactone 5-oxo-1,2-campholide with (S,S) configuration, that presumably undergoes spontaneous hydrolysis to form 2-oxo-Delta(3)-4,5,5-trimethylcyclopentenylacetate (PubMed:23524667). Is also able to convert (-)-camphor to the corresponding lactone in vitro (PubMed:23524667, PubMed:22286514, PubMed:8515237). Shows no conversion of (+)-camphor, (+)-fenchone, (-)-fenchone, and (+)-nopinone. Acts on other bicyclic ketones but very poorly on a few 2- and 4-substituted monocyclic ketones (PubMed:23524667).^[1] ^[2] ^[3] ^[4]

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.
