Accepted name: 1-deoxypentalenic acid 11β-hydroxylase
Reaction: 1-deoxypentalenate + 2-oxoglutarate + O2 = 1-deoxy-11β-hydroxypentalenate + succinate + CO2
Glossary: 1-deoxypentalenate = (1R,3aR,5aS,8aR)-1,7,7-trimethyl-1,2,3,3a,5a,6,7,8-octahydrocyclopenta[c]pentalene-4-carboxylate
1-deoxy-11β-hydroxypentalenate = (1S,2R,3aR,5aS,8aR)-2-hydroxy-1,7,7-trimethyl-1,2,3,3a,5a,6,7,8-octahydrocyclopenta[c]pentalene-4-carboxylate
Other name(s): ptlH (gene name); sav2991 (gene name); pntH (gene name)
Systematic name: 1-deoxypentalenic acid,2-oxoglutarate:oxygen oxidoreductase
Comments: The enzyme requires Fe(II) and ascorbate. Isolated from the bacterium Streptomyces avermitilis. Part of the pathway for pentalenolactone biosynthesis.
