CTP:2,3-di-O-geranylgeranyl-sn-glycero-1-phosphate cytidyltransferase
CDP-2,3-bis-O-(geranylgeranyl)-sn-glycerol synthase
CTP:2,3-bis-O-(geranylgeranyl)-sn-glycero-1-phosphate cytidylyltransferase
CDP-unsaturated archaeol synthase

carS (gene name)
Systematic name:
CTP:2,3-bis-(O-geranylgeranyl)-sn-glycerol 1-phosphate cytidylyltransferase




This enzyme catalyses one of the steps in the biosynthesis of polar lipids in Archaea, which are characterized by having an sn-glycero-1-phosphate backbone rather than an sn-glycero-3-phosphate backbone as is found in bacteria and eukaryotes [1]. The enzyme requires Mg2+ and K+ for maximal activity [1].
