CC -!- FUNCTION: Catalyzes the dephosphorylation of diacylglycerol diphosphate
CC (DGPP) to phosphatidate (PA) and the subsequent dephosphorylation of PA
CC to diacylglycerol (DAG). Also has undecaprenyl pyrophosphate
CC phosphatase activity, required for the biosynthesis of the lipid
CC carrier undecaprenyl phosphate. Can also use lysophosphatidic acid
CC (LPA) and phosphatidylglycerophosphate as substrates. The pattern of
CC activities varies according to subcellular location, PGP phosphatase
CC activity is higher in the cytoplasmic membrane, whereas PA and LPA
CC phosphatase activities are higher in the outer membrane. Activity is
CC independent of a divalent cation ion and insensitive to inhibition by
CC N-ethylmaleimide (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1,2-diacyl-sn-glycero-3-phospho-(1'-sn-glycero-3'-phosphate) +

CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58405, ChEBI:CHEBI:60392; EC=3.6.1.27;
CC -!- PATHWAY: Phospholipid metabolism; phosphatidylglycerol biosynthesis;
CC phosphatidylglycerol from CDP-diacylglycerol: step 2/2.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Multi-pass
CC membrane protein {ECO:0000250}. Cell outer membrane {ECO:0000250};
CC Multi-pass membrane protein {ECO:0000250}.
CC -!- PTM: The N-terminus is blocked. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the PA-phosphatase related phosphoesterase
CC family. {ECO:0000305}.
