EC 2.7.1.174     
Accepted name: diacylglycerol kinase (CTP)
Reaction: CTP + 1,2-diacyl-sn-glycerol = CDP + 1,2-diacyl-sn-glycerol 3-phosphate
Glossary: 1,2-diacyl-sn-glycerol 3-phosphate = phosphatidate
Other name(s): DAG kinase; CTP-dependent diacylglycerol kinase; diglyceride kinase (ambiguous); DGK1 (gene name); diacylglycerol kinase (CTP dependent)
Systematic name: CTP:1,2-diacyl-sn-glycerol 3-phosphotransferase
Comments: Requires Ca2+ or Mg2+ for activity. Involved in synthesis of membrane phospholipids and the neutral lipid triacylglycerol. Unlike the diacylglycerol kinases from bacteria, plants, and animals [cf. EC 2.7.1.107, diacylglycerol kinase (ATP)], the enzyme from Saccharomyces cerevisiae utilizes CTP. The enzyme can also use dCTP, but not ATP, GTP or UTP.
