CC   -!- FUNCTION: Esterifies acyl-group from acyl-ACP to the sn-1 position of
CC       glycerol-3-phosphate. The enzyme from chilling-resistant plants
CC       discriminates against non-fluid palmitic acid and selects oleic acid
CC       whereas the enzyme from sensitive plants accepts both fatty acids. This
CC       is an oleate-selective acyltransferase.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=sn-glycerol 3-phosphate + an acyl-CoA = a 1-acyl-sn-glycero-3-
CC         phosphate + CoA; Xref=Rhea:RHEA:15325, ChEBI:CHEBI:57287,
CC         ChEBI:CHEBI:57597, ChEBI:CHEBI:57970, ChEBI:CHEBI:58342; EC=2.3.1.15;
CC   -!- PATHWAY: Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-
CC       diacylglycerol from sn-glycerol 3-phosphate: step 1/3.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma.
CC   -!- DOMAIN: The HXXXXD motif is essential for acyltransferase activity and
CC       may constitute the binding site for the phosphate moiety of the
CC       glycerol-3-phosphate. {ECO:0000250}.
CC   -!- PTM: The N-terminus is blocked.
CC   -!- SIMILARITY: Belongs to the GPAT/DAPAT family. {ECO:0000305}.
