EC 3.1.2.31

Accepted name: dihydromonacolin L-[lovastatin nonaketide synthase] thioesterase

Reaction: dihydromonacolin L-[lovastatin nonaketide synthase] + H2O = holo-[lovastatin nonaketide synthase] + dihydromonacolin L acid

Glossary: dihydromonacolin L acid = (3R,5R)-7-[(1S,2S,4aR,6R,8aS)-2,6-dimethyl-1,2,4a,5,6,7,8,8a-octahydronaphthalen-1-yl]-3,5-dihydroxyheptanoate

Other name(s): LovG

Systematic name: dihydromonacolin L-[lovastatin nonaketide synthase] hydrolase

Comments: Dihydromonacolin L acid is synthesized while bound to an acyl-carrier protein domain of the lovastatin nonaketide synthase (EC 2.3.1.161). Since that enzyme lacks a thioesterase domain, release of the dihydromonacolin L acid moiety from the polyketide synthase requires this dedicated enzyme.
