| Accepted name: |
hydroxysqualene dehydroxylase |
| Reaction: |
squalene + FAD + H2O = hydroxysqualene + FADH2 |
| Glossary: |
hydroxysqualene = (6E,10E,12R,14E,18E)-2,6,10,15,19,23-hexamethyltetracosa-2,6,10,14,18,22-hexaen-12-ol |
| Other name(s): |
hpnE (gene name) |
| Systematic name: |
squalene:FAD oxidoreductase (hydroxylating) |
| Comments: |
This enzyme, isolated from the bacteria Rhodopseudomonas palustris and Zymomonas mobilis, participates, along with EC 2.5.1.103, presqualene diphosphate synthase, and EC 4.2.3.156, hydroxysqualene synthase, in the conversion of all-trans-farnesyl diphosphate to squalene. Eukaryotes achieve the same goal in a single step, catalysed by EC 2.5.1.21, squalene synthase. |
