9.B.273. The Phosphatidate Cytidylyltransferase (PCT) Family
Phosphatidate cytidylyltransferases, or diacyl glyceride syntehtases, catalyze the reaction of CTP and phosphatidate to form diphosphate and CDP-diacylglycerol, a central liponucleotide for phospholipid biosynthesis. These proteins are of about 270 aas in length and have about 8 TMSs.
