CC -!- FUNCTION: Catalyzes triacylglycerol (TAG) formation by an acyl-CoA
CC independent pathway. The enzyme specifically transfers acyl groups from
CC the sn-2 position of a phospholipid to diacylglycerol (DAG), thus
CC forming an sn-1-lysophospholipid. Plays a major role in triacylglycerol
CC formation at log phase (PubMed:12963726, PubMed:26990381). Involved in
CC lipid particle synthesis from the endoplasmic reticulum, promoting
CC localized TAG production at discrete ER subdomains (PubMed:26990381,
CC PubMed:28011631). {ECO:0000269|PubMed:12963726,
CC ECO:0000269|PubMed:26990381, ECO:0000269|PubMed:28011631}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-sn-glycerol + a glycerophospholipid = a
CC monoacylglycerophospholipid + a triacyl-sn-glycerol;
CC Xref=Rhea:RHEA:14057, ChEBI:CHEBI:17815, ChEBI:CHEBI:64615,
CC ChEBI:CHEBI:136912, ChEBI:CHEBI:136913; EC=2.3.1.158;
CC Evidence={ECO:0000269|PubMed:12963726};
CC -!- PATHWAY: Glycerolipid metabolism; triacylglycerol biosynthesis.
CC {ECO:0000305|PubMed:12963726}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:12963726, ECO:0000269|PubMed:16823372}; Single-pass
CC type II membrane protein {ECO:0000255}.
CC -!- DISRUPTION PHENOTYPE: Has reduced whole-cell and lipid droplet (LD) TAG
CC levels. Cells lacking both TAG synthase genes (plh1 and dga1) have no
CC LDs and exhibit defects in spore germination and in spore wall
CC integrity. {ECO:0000269|PubMed:26990381, ECO:0000269|PubMed:28011631}.
CC -!- SIMILARITY: Belongs to the AB hydrolase superfamily. Lipase family.
CC {ECO:0000305}.
