ID 2.5.1.41 DE phosphoglycerol geranylgeranyltransferase. AN (S)-3-O-geranylgeranylglyceryl phosphate synthase. AN GGGPS. AN GGGP synthase. CA (2E,6E,10E)-geranylgeranyl diphosphate + sn-glycerol 1-phosphate = CA diphosphate + sn-3-O-(geranylgeranyl)glycerol 1-phosphate. CC -!- Catalyzes the first pathway-specific step in the biosynthesis of the CC core membrane diether lipids in archaebacteria. CC -!- It catalyzes the alkylation of the primary hydroxy group in CC sn-glycerol 1-phosphate by geranylgeranyl diphosphate (GGPP) in a CC prenyltransfer reaction where a hydroxy group is the nucleophile in CC the acceptor substrate. CC -!- The other enzymes involved in the biosynthesis of polar lipids in CC archaea are EC 1.1.1.261, EC 2.5.1.42 and EC 2.7.7.67, which lead to CC the formation of CDP-unsaturated archaeol. CC -!- The final step in the pathway involves the addition of L-serine, with CC concomitant removal of CMP, leading to the production of unsaturated CC archaetidylserine.
