1.14.14.155

Accepted name:

3,6-diketocamphane 1,2-monooxygenase

Reaction:

(–)-bornane-2,5-dione + O₂ + FMNH₂ = (–)-5-oxo-1,2-campholide + FMN + H₂O

Glossary:

(–)-bornane-2,5-dione = 3,6-diketocamphane

Other name(s):

3,6-diketocamphane lactonizing enzyme; 3,6-DKCMO

Systematic name:

(–)-bornane-2,5-dione,FMNH₂:oxygen oxidoreductase (1,2-lactonizing)

Comments:

A Baeyer-Villiger monooxygenase isolated from camphor-grown strains of Pseudomonas putida and encoded on the cam plasmid. Involved in the degradation of (–)-camphor. Requires a dedicated NADH—FMN reductase [cf. EC 1.5.1.42, FMN reductase (NADH)] [1,2]. The product spontaneously converts to [(1R)-2,2,3-trimethyl-5-oxocyclopent-3-enyl]acetate.
