HMGS

Gene
HMGS
Protein
Hydroxymethylglutaryl-CoA synthase
Organism
Arabidopsis thaliana
Length
461 amino acids
Function
This enzyme condenses acetyl-CoA with acetoacetyl-CoA to form HMG-CoA, which is the substrate for HMG-CoA reductase. Devoided of acetoacetyl-CoA thiolase (AACT) activity. Required for the development of both tapetosomes and elaioplasts in tapetal cells and for pollen viability during pollen tube elongation.
Similarity
Belongs to the thiolase-like superfamily. HMG-CoA synthase family.
