ID   2.3.1.158
DE   phospholipid:diacylglycerol acyltransferase.
AN   PDAT.
CA   a 1,2-diacyl-sn-glycerol + a glycerophospholipid =
CA   a monoacylglycerophospholipid + a triacyl-sn-glycerol.
CC   -!- This enzyme differs from EC 2.3.1.20 by synthesizing triacylglycerol
CC       using an acyl-CoA-independent mechanism.
CC   -!- The specificity of the enzyme for the acyl group in the phospholipid
CC       varies with species, e.g., the enzyme from castor bean (Ricinus
CC       communis) preferentially incorporates vernoloyl (12,13-epoxyoctadec-
CC       9-enoyl) groups into triacylglycerol, whereas that from the hawk's
CC       beard (Crepis palaestina) incorporates both ricinoleoyl
CC       (12-hydroxyoctadec-9-enoyl) and vernoloyl groups.
CC   -!- The enzyme from the yeast Saccharomyces cerevisiae specifically
CC       transfers acyl groups from the sn-2 position of the phospholipid to
CC       diacylglycerol, thus forming an sn-1-lysophospholipid.
