case <OC:Archaea> | |
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. |
CATALYTIC ACTIVITY | Reaction=sn-glycerol 1-phosphate + (2E,6E,10E)-geranylgeranyl diphosphate = sn-3-O-(geranylgeranyl)glycerol 1-phosphate + diphosphate; Xref=Rhea:RHEA:23404, ChEBI:CHEBI:33019, ChEBI:CHEBI:57677, ChEBI:CHEBI:57685, ChEBI:CHEBI:58756; EC=2.5.1.41; |

else case <OC:Bacillales> | |
FUNCTION | Prenyltransferase that catalyzes in vivo the transfer of the heptaprenyl moiety of heptaprenyl pyrophosphate (HepPP; 35 carbon atoms) to the C3 hydroxyl of sn-glycerol-1-phosphate (G1P), producing heptaprenylglyceryl phosphate (HepGP). This reaction is an ether-bond- formation step in the biosynthesis of archaea-type G1P-based membrane lipids found in Bacillales. |
CATALYTIC ACTIVITY | Reaction=sn-glycerol 1-phosphate + all-trans-heptaprenyl diphosphate = 3-heptaprenyl-sn-glycero-1-phosphate + diphosphate; Xref=Rhea:RHEA:33495, ChEBI:CHEBI:33019, ChEBI:CHEBI:57685, ChEBI:CHEBI:58206, ChEBI:CHEBI:64781; EC=2.5.1.n9; |

Comments | Bacteroidota have GGGPS activity like the archaeal enzyme, but the physiological function is unknown (PubMed=24684232). Two phylogenetic subgroups (I and II) exist within the family. They use alternative amino acid residues to bind G1P (PubMed=24684232). Many Halobacteria possess two paralogs of GGGPS. |
