Glossary: (2,2,3-trimethyl-5-oxocyclopent-3-enyl)acetyl-CoA = 2-oxo-Δ3-4,5,5-trimethylcyclopentenylacetyl-CoA
Other name(s): 2-oxo-Δ3-4,5,5-trimethylcyclopentenylacetyl-CoA monooxygenase; 2-oxo-Δ3-4,5,5-trimethylcyclopentenylacetyl-CoA 1,2-monooxygenase; OTEMO
Systematic name: [(1R)-2,2,3-trimethyl-5-oxocyclopent-3-enyl]acetyl-CoA,NADPH:oxygen oxidoreductase (1,5-lactonizing)
Comments: A FAD dependent enzyme isolated from Pseudomonas putida. Forms part of the catabolism pathway of camphor. It acts on the CoA ester in preference to the free acid.
