General annotation (Comments)

Function	Functions in the biosynthesis of the anionic phospholipids phosphatidylglycerol and cardiolipin. Ref.1
Catalytic activity	CDP-diacylglycerol + sn-glycerol 3-phosphate = CMP + 3(3-sn-phosphatidyl)-sn-glycerol 1-phosphate. Ref.1 Ref.2
Enzyme regulation	Activated by calcium and magnesium and inhibited by other bivalent cations. Ref.2
Pathway	Phospholipid metabolism; phosphatidylglycerol biosynthesis; phosphatidylglycerol from CDP-diacylglycerol: step 1/2.
Subcellular location	Mitochondrion Ref.2.
Sequence similarities	Belongs to the CDP-alcohol phosphatidyltransferase class-II family. Contains 2 PLD phosphodiesterase domains.
Biophysicochemical properties	Kinetic parameters: KM=288 µM for CDP-diacylglycerol Vmax=13.6 µmol/min/mg enzyme
