| Comment(s) |
|---|
- Carries out the second prenyltransfer reaction involved in the
formation of polar membrane lipids in archaea.
- 4-hydroxybenzoate, 1,4-dihydroxy 2-naphthoate, homogentisate and
alpha-glycerophosphate cannot act as prenyl-acceptor substrates.
- The other enzymes involved in the biosynthesis of polar lipids in
archaea are EC 1.1.1.261, EC 2.5.1.41, which, together with this
enzyme, alkylates the hydroxy groups of glycerol 1-phosphate to yield
unsaturated archaetidic acid, which is acted upon by EC 2.7.7.67 to
form 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.
