CC   -!- FUNCTION: Catalyzes the phosphorylation of diacylglycerol (DAG) into
CC       phosphatidic acid. Is a key enzyme involved in the production of
CC       lipoteichoic acid by reintroducing DAG formed from the breakdown of
CC       membrane phospholipids into the phosphatidylglycerol biosynthetic
CC       pathway. {ECO:0000250|UniProtKB:Q6GFF9}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 1,2-diacyl-sn-glycerol + ATP = a 1,2-diacyl-sn-glycero-3-
CC         phosphate + ADP + H(+); Xref=Rhea:RHEA:10272, ChEBI:CHEBI:15378,

CC         Evidence={ECO:0000250|UniProtKB:Q6GFF9};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:Q6GFF9};
CC       Note=Binds 1 Mg(2+) ion per subunit. This ion appears to have a
CC       structural role and is required for catalytic activity.
CC       {ECO:0000250|UniProtKB:Q6GFF9};
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q6GFF9}.
CC   -!- SIMILARITY: Belongs to the diacylglycerol/lipid kinase family.
CC       {ECO:0000305}.
