Glossary: 1-deoxy-11-oxopentalenate = (1S,3aR,5aS)-1,7,7-trimethyl-2-oxo-1,2,3,3a,5a,6,7,8-octahydrocyclopenta[c]pentalene-4-carboxylate
pentalenolactone D = (1S,4aR,6aS,9aR)-1,8,8-trimethyl-2-oxo-1,2,4,4a,6a,7,8,9-octahydropentaleno[1,6a-c]pyran-5-carboxylate
Other name(s): penE (gene name); pntE (gene name)
Systematic name: 1-deoxy-11-oxopentalenate,NADH:oxygen oxidoreductase (pentalenolactone-D-forming)
Comments: A FAD-dependent oxygenase. Isolated from the bacteria Streptomyces exfoliatus and Streptomyces arenae. The ketone undergoes a biological Baeyer-Villiger reaction. Part of the pathway of pentalenolactone biosynthesis.
