CC -!- FUNCTION: Trans-enoyl reductase; part of the gene cluster that mediates
CC the biosynthesis of lovastatin (also known as mevinolin, mevacor or
CC monacolin K), a hypolipidemic inhibitor of (3S)-hydroxymethylglutaryl-
CC coenzyme A (HMG-CoA) reductase (HMGR) (PubMed:10334994,
CC PubMed:12929390, PubMed:21495633). The first step in the biosynthesis
CC of lovastatin is the production of dihydromonacolin L acid by the
CC lovastatin nonaketide synthase lovB and the trans-acting enoyl
CC reductase lovC via condensation of one acetyl-CoA unit and 8 malonyl-
CC CoA units (PubMed:10334994, PubMed:10381407, PubMed:19900898,
CC PubMed:22733743). Dihydromonacolin L acid is released from lovB by the
CC thioesterase lovG (PubMed:23653178). Next, dihydromonacolin L acid is
CC oxidized by the dihydromonacolin L monooxygenase lovA twice to form
CC monacolin J acid (PubMed:12929390, PubMed:21495633). The 2-
CC methylbutyrate moiety of lovastatin is synthesized by the lovastatin
CC diketide synthase lovF via condensation of one acetyl-CoA unit and one
CC malonyl-CoA unit (PubMed:19530726, PubMed:21069965). Finally, the
CC covalent attachment of this moiety to monacolin J acid is catalyzed by
CC the transesterase lovD to yield lovastatin (PubMed:10334994,
CC PubMed:17113998, PubMed:18988191, PubMed:19875080, PubMed:24727900).
CC LovD has broad substrate specificity and can also convert monacolin J
CC to simvastatin using alpha-dimethylbutanoyl-S-methyl-3-
CC mercaptopropionate (DMB-S-MMP) as the thioester acyl donor, and can
CC also catalyze the reverse reaction and function as hydrolase in vitro
CC (PubMed:19875080). LovD has much higher activity with LovF-bound 2-
CC methylbutanoate than with free diketide substrates (PubMed:21069965).

CC -!- DISRUPTION PHENOTYPE: Loss of lovastatin biosynthesis.
CC {ECO:0000269|PubMed:10334994}.
CC -!- BIOTECHNOLOGY: Lovastatin acts as a hypolipidemic agent that works as
CC inhibitor of (3S)-hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase
CC (HMGR) which reduces HMG-CoA to mevalonate and is the key step in
CC cholesterol biosynthesis (PubMed:6933445). Lovastatin, simvastatin and
CC related compounds are widely used to treat hypercholesteremia and
CC reduce the risk of cardiovascular disease (PubMed:6933445).
CC Furthermore, statins such as lovastatin were found to be anticancer
CC agents (PubMed:29236027, PubMed:29932104).

CC family. {ECO:0000305}.
