Protein

Diacylglycerol kinase

Gene

dagK

Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Catalyzes the phosphorylation of diacylglycerol (DAG) into phosphatidic acid. Is involved in the biosynthesis of phosphatidylinositol mannosides (PIMs), probably via a role in the biosynthesis of phosphatidylinositol (PI), a PIM precursor, which is derived from phosphatidic acid (By similarity).By similarity

Catalytic activityi

ATP + 1,2-diacyl-sn-glycerol = ADP + 1,2-diacyl-sn-glycerol 3-phosphate.

Cofactori

Mg2+By similarityNote: Binds 1 Mg2+ ion per subunit. This ion appears to have a structural role and is required for catalytic activity.By similarity
