Comments

FUNCTION: This transmembrane glycoprotein is involved in the control of cholesterol biosynthesis. It is the rate-limiting enzyme of sterol biosynthesis.
CATALYTIC ACTIVITY: (R)-mevalonate + CoA + 2 NADP⁺ = (S)-3-hydroxy-3-methylglutaryl-CoA + 2 NADPH.
ENZYME REGULATION: The activity of HMG-CoA-reductase is suppressed by exogenous mevalonate.
PATHWAY: Metabolic intermediate biosynthesis; mevalonic acid biosynthesis; (R)-mevalonic acid from acetyl-CoA: step 3/3 .
SUBUNIT: Homodimer.
SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass membrane protein.
SIMILARITY: Belongs to the HMG-CoA reductase family.
