Protein attributes

Sequence length	604 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. Possible role in plant defense mechanisms as well as in the cell cycle.
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; Multi-pass membrane protein.
Tissue specificity	Found in protoplasts and leaves submitted to stress. Low levels found in apexes, anthers and roots.
Developmental stage	Expressed at highest levels during the G0-G1 transition in the cell cycle of mesophyll protoplasts.
Induction	In leaves, by wounding, elicitation, bacterial or fungal infection.
Sequence similarities	Belongs to the HMG-CoA reductase family.
