⇱ ENZYME - 2.5.1.103 presqualene diphosphate synthase

ENZYME entry: EC 2.5.1.103

PURL: https://purl.expasy.org/enzyme/EC/2.5.1.103
Accepted Name
presqualene diphosphate synthase
Reaction catalysed
2 (2E,6E)-farnesyl diphosphate = presqualene diphosphate + diphosphate
Comment(s)
  • Isolated from the green alga Botryococcus braunii BOT22.
  • Unlike EC 2.5.1.21, where squalene is formed in one step from farnesyl diphosphate, in this alga the intermediate presqualene diphosphate is generated and released by this enzyme.
  • This compound is then converted into either squalene (by EC 1.3.1.96) or botryococcene (EC 1.3.1.97).
