Protein
O-acyltransferase WSD
Gene
wax-dgaT, ACIAD0832
Organism
Acinetobacter baylyi (strain ATCC 33305 / BD413 / ADP1)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at protein leveli

Functioni

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.

Catalytic activityi

Acyl-CoA + a long-chain alcohol = CoA + a long-chain ester.
Acyl-CoA + 1,2-diacylglycerol = CoA + triacylglycerol.

Kineticsi

  1. KM=15.6 µM for palmitoyl-CoA (C(16), in wax synthase)1 Publication
  2. KM=21.1 µM for palmitoyl-CoA (diacylglycerol acyltransferase)
