Protein
Diacylglycerol O-acyltransferase 3
Organism
Arabidopsis thaliana
Function
Involved in triacylglycerol (TAG) biosynthesis (PubMed:22760209, PubMed:30467384). Catalyzes the acylation of the sn-3 hydroxy group of sn-1,2-diacylglycerol using acyl-CoA (PubMed:22760209, PubMed:30467384). May preferentially use linolenoyl-CoA as substrate and to a lesser extent linoleoyl-CoA (PubMed:22760209). May contribute to the active recycling of linoleate and linolenate into TAG when seed oil breakdown is blocked (PubMed:22760209).
Similarity
Belongs to the diacylglycerol acyltransferase family.
