ENZYME entry: EC

Accepted Name
Presqualene diphosphate synthase.
Reaction catalysed
2 (2E,6E)-farnesyl diphosphate <=> presqualene diphosphate + diphosphate
  • Isolated from the green alga Botryococcus braunii BOT22.
  • Unlike EC, 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 or botryococcene (EC
