Protein
O-acyltransferase WSD
Organism
Acinetobacter baylyi (strain ATCC 33305 / BD413 / ADP1)
Function
Bifunctional wax ester synthase/diacylglycerol acyltransferase (WS and DGAT). Catalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. Required for storage lipid synthesis. WS uses C(12)-CoA to C(18)-CoA substrates whereas DGAT prefers C(20)-CoA. Upon expression in E.coli and Pseudomonas citronellolis (DSM 50332) both WS and DGAT activities increase.
Similarity
Belongs to the long-chain O-acyltransferase family.
