CC   -!- FUNCTION: Esterase; part of the gene cluster that mediates the
CC       biosynthesis of compactin, also known as mevastatin or ML-236B, and
CC       which acts as a potent competitive inhibitor of HMG-CoA reductase
CC       (PubMed:12172803, PubMed:12242508). Compactin biosynthesis is performed
CC       in two stages (PubMed:12172803). The first stage is catalyzed by the
CC       nonaketide synthase mlcA, which belongs to type I polyketide synthases
CC       and catalyzes the iterative nine-step formation of the polyketide
CC       (PubMed:12172803). This PKS stage is completed by the action of
CC       dehydrogenase mlcG, which catalyzes the NADPH-dependent reduction of
CC       the unsaturated tetra-, penta- and heptaketide intermediates that arise
CC       during the mlcA-mediated biosynthesis of the nonaketide chain and leads
CC       to dihydro-ML-236C carboxylate (PubMed:12172803). Covalently bound
CC       dihydro-ML-236C carboxylate is released from mlcA by the mlcF esterase
CC       (PubMed:12172803). Conversion of dihydro-ML-236C carboxylate into ML-
CC       236A carboxylate is subsequently performed with the participation of
CC       molecular oxygen and P450 monoogygenase mlcC (PubMed:12172803).
CC       Finally, mlcH performs the conversion of ML-236A carboxylate to ML-
CC       236B/compactin carboxylate through the addition of the side-chain
CC       diketide moiety produced by the diketide synthase mlcB
CC       (PubMed:12172803). {ECO:0000269|PubMed:12172803,
CC       ECO:0000269|PubMed:12242508}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=dihydro-ML-236C-[compactin nonaketide synthase] + H2O =
CC         dihydro-ML-236C carboxylate + H(+) + holo-[compactin nonaketide
CC         synthase]; Xref=Rhea:RHEA:57616, Rhea:RHEA-COMP:14940, Rhea:RHEA-

CC         ChEBI:CHEBI:142039, ChEBI:CHEBI:142045; Evidence={ECO:0000305};
CC   -!- PATHWAY: Polyketide biosynthesis. {ECO:0000305}.
CC   -!- INDUCTION: Expression is induced at the beginning of the stationary
CC       phase, which is consistent with the timing of compactin production
CC       (PubMed:12172803). Expression is controlled by the ML-236B/compactin
CC       cluster transcription regulator mlcR (PubMed:12436257).
CC       {ECO:0000269|PubMed:12172803, ECO:0000269|PubMed:12436257}.
CC   -!- BIOTECHNOLOGY: Compactin (also known as mevastatin or ML-236B) and the
CC       intermediary metabolites Ml-236C and ML-236A are inhibitors of HMG-CoA
CC       reductase involved in cholesterogenesis (PubMed:1010803). Their
CC       hypocholesterolemic activity might be useful for lowering cholesterol
CC       levels in the blood and reduce artherosclerosis and coronary heart
CC       disease (PubMed:1010803). {ECO:0000269|PubMed:1010803}.
CC   -!- SIMILARITY: Belongs to the LovG family. {ECO:0000305}.
