FunFam 1: Heptaprenylglyceryl phosphate synthase

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Heptaprenylglyceryl phosphate synthase. [EC: 2.5.1.n9]
All-trans-heptaprenyl diphosphate + sn-glycerol 1-phosphate = diphosphate + sn-3-O-(all-trans-heptaprenyl)glycerol 1-phosphate.
  • Part of the pathway in the biosynthesis of archaea-type G1P-based membrane lipids found in Bacillales.

Phosphoglycerol geranylgeranyltransferase. [EC: 2.5.1.41]
Geranylgeranyl diphosphate + sn-glycerol 1-phosphate = diphosphate + sn-3-O-(geranylgeranyl)glycerol 1-phosphate.
  • Catalyzes the first pathway-specific step in the biosynthesis of the core membrane diether lipids in archaebacteria.
  • It catalyzes the alkylation of the primary hydroxy group in sn-glycerol 1-phosphate by geranylgeranyl diphosphate (GGPP) in a prenyltransfer reaction where a hydroxy group is the nucleophile in the acceptor substrate.
  • The other enzymes involved in the biosynthesis of polar lipids in archaea are EC 1.1.1.261, EC 2.5.1.42 and EC 2.7.7.67, which lead to the formation of CDP-unsaturated archaeol.
  • The final step in the pathway involves the addition of L-serine, with concomitant removal of CMP, leading to the production of unsaturated archaetidylserine.
