Protein
Acyl-CoA--sterol O-acyltransferase 1
Organism
Arabidopsis thaliana
Function
Involved in the esterification of cycloartenol. Not implicated in the formation of sterol esters in flowers or during seed maturation. Has a substrate preference toward saturated fatty acyl donors (16:0 > 18:0 > 16:1 > 18:1). Does not require triacyglycerols (TAGs) as a fatty acyl donor, and is unable to acylate diacylglycerol to produce TAG.
Similarity
Belongs to the wax synthase family.
