Protein
Diacylglycerol kinase
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Function
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. Is also able to phosphorylate other various amphipathic lipids of host and bacterial origin in vitro, such as ceramide.
Similarity
Belongs to the diacylglycerol/lipid kinase family.
