Protein attributes

Sequence length	532 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Catalyzes the synthesis of mevalonate. The specific precursor of all isoprenoid compounds present in plants.
Catalytic activity	(R)-mevalonate + CoA + 2 NADP(+) = (S)-3-hydroxy-3-methylglutaryl-CoA + 2 NADPH.
Pathway	Metabolic intermediate biosynthesis; mevalonic acid biosynthesis; (R)-mevalonic acid from acetyl-CoA: step 3/3.
Subcellular location	Endoplasmic reticulum membrane; Single-pass membrane protein.
Sequence similarities	Belongs to the HMG-CoA reductase family.
Sequence caution	The sequence BAF09829.1 differs from that shown. Reason: Erroneous gene model prediction.
