2.7.8.39

Accepted name:

archaetidylinositol phosphate synthase

Reaction:

CDP-2,3-bis-(O-phytanyl)-sn-glycerol + 1L-myo-inositol 1-phosphate = CMP + 1-archaetidyl-1D-myo-inositol 3-phosphate

Glossary:

1L-myo-inositol 1-phosphate = 1D-myo-inositol 3-phosphate
CDP-2,3-bis-(O-phytanyl)-sn-glycerol = CDP-2,3-di-(O-phytanyl)-sn-glycerol = CDP-archaeol
1-archaetidyl-1D-myo-inositol 3-phosphate = archaetidyl-myo-inositol 1-phosphate

Other name(s):

AIP synthase

Systematic name:

CDP-2,3-bis-(O-phytanyl)-sn-glycerol:1L-myo-inositol 1-phosphate 1-sn-archaetidyltransferase

Comments:

Requires Mg²⁺ or Mn²⁺ for activity. The enzyme is involved in biosynthesis of archaetidyl-myo-inositol, a compound essential for glycolipid biosynthesis in archaea.
