Igni_0425

Gene
Igni_0425
Protein
Geranylgeranylglyceryl phosphate synthase
Organism
Ignicoccus hospitalis (strain KIN4/I / DSM 18386 / JCM 14125)
Length
245 amino acids
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 II subfamily.
