CTP:phosphocholine cytidylyltransferase; CTP:phosphocholine cytidylyltransferase (CCT) catalyzes the condensation of CTP and phosphocholine to form CDP-choline as the rate-limiting and regulatory step in the CDP-choline pathway. CCT is unique in that its enzymatic activity is regulated by the extent of its association with membrane structures. A current model posts that the elastic stress of the bilayer curvature is sensed by CCT and this governs the degree of membrane association, thus providing a mechanism for both positive and negative regulation of activity.

CTP:phosphoethanolamine cytidylyltransferase (ECT); CTP:phosphoethanolamine cytidylyltransferase (ECT) catalyzes the conversion of phosphoethanolamine to CDP-ethanolamine as part of the CDP-ethanolamine biosynthesis pathway. ECT expression in hepatocytes is localized predominantly to areas of the cytoplasm that are rich in rough endoplasmic reticulum. Several ECTs, including yeast and human ECT, have large repetitive sequences located within their N- and C-termini.

Many of these proteins are known to use CTP or ATP and release pyrophosphate.

glycerol-3-phosphate cytidylyltransferase; Glycerol-3-phosphate cytidylyltransferase,(CDP-glycerol pyrophosphorylase). Glycerol-3-phosphate cytidyltransferase acts in pathways of teichoic acid biosynthesis. Teichoic acids are substituted polymers, linked by phosphodiester bonds, of glycerol, ribitol, etc. An example is poly(glycerol phosphate), the major teichoic acid of the Bacillus subtilis cell wall. Most, but not all, species encoding proteins in this family are Gram-positive bacteria. A closely related protein assigned a different function experimentally is a human ethanolamine-phosphate cytidylyltransferase.

N-terminal domain of RfaE; RfaE is a protein involved in the biosynthesis of ADP-L-glycero-D-manno-heptose, a precursor for LPS inner core biosynthesis. RfaE is a bifunctional protein in Escherichia coli, and separate proteins in other organisms. Domain I is suggested to act in D-glycero-D-manno-heptose 1-phosphate biosynthesis, while domain II (this family) adds ADP to yield ADP-D-glycero-D-manno-heptose .
