Protein
Geranylgeranylglyceryl phosphate synthase
Organism
Methanosphaerula palustris (strain ATCC BAA-1556 / DSM 19958 / E1-9c)
Function
Prenyltransferase that catalyzes the transfer of the geranylgeranyl moiety of geranylgeranyl diphosphate (GGPP) to the C3 hydroxyl of sn-glycerol-1-phosphate (G1P). This reaction is the first ether-bond-formation step in the biosynthesis of archaeal membrane lipids.
Similarity
Belongs to the GGGP/HepGP synthase family. Group I subfamily.
