ENZYME entry: EC 4.2.3.156

Accepted Name
Hydroxysqualene synthase.
Reaction catalysed
Presqualene diphosphate + H(2)O <=> hydroxysqualene + diphosphate
Comment(s)
  • This enzyme, isolated from the bacteria Rhodopseudomonas palustris and Zymomonas mobilis, participates, along with EC 2.5.1.103 and EC 1.17.18.1, in the conversion of all-trans-farnesyl diphosphate to squalene.
  • Eukaryotes achieve the same goal in a single step, catalyzed by EC 2.5.1.21.
