CC -!- FUNCTION: HMG-CoA reductase; part of the first module of ergosterol
CC biosynthesis pathway that includes the early steps of the pathway,
CC conserved across all eukaryotes, and which results in the formation of
CC mevalonate from acetyl-coenzyme A (acetyl-CoA) (Probable). In this
CC module, the cytosolic acetyl-CoA acetyltransferase catalyzes the
CC formation of acetoacetyl-CoA (By similarity). The
CC hydroxymethylglutaryl-CoA synthase then condenses acetyl-CoA with
CC acetoacetyl-CoA to form HMG-CoA (By similarity). The rate-limiting step
CC of the early module is the reduction to mevalonate by the 3-hydroxy-3-
CC methylglutaryl-coenzyme A (HMG-CoA) reductase hmgA (Probable).
CC {ECO:0000250|UniProtKB:Q4WHZ1, ECO:0000305|Ref.2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-mevalonate + CoA + 2 NADP(+) = (3S)-hydroxy-3-
CC methylglutaryl-CoA + 2 H(+) + 2 NADPH; Xref=Rhea:RHEA:15989,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:36464, ChEBI:CHEBI:43074,
CC ChEBI:CHEBI:57287, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=1.1.1.34;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10003, ECO:0000305|Ref.2};
CC -!- PATHWAY: Metabolic intermediate biosynthesis; (R)-mevalonate
CC biosynthesis; (R)-mevalonate from acetyl-CoA: step 3/3.
CC {ECO:0000305|Ref.2}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000305};
CC Multi-pass membrane protein {ECO:0000255}.
CC -!- SIMILARITY: Belongs to the HMG-CoA reductase family. {ECO:0000305}.
