Protein

Diacylglycerol kinase

Gene

dagK

Organism
Staphylococcus aureus (strain Newman)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the phosphorylation of diacylglycerol (DAG) into phosphatidic acid. Is a key enzyme involved in the production of lipoteichoic acid by reintroducing DAG formed from the breakdown of membrane phospholipids into the phosphatidylglycerol biosynthetic pathway (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
