Enzyme Information
| 5.4.99.17 |
Squalene--hopene cyclase.
based on mapping to UniProt P33247
Squalene = hop-22(29)-ene.
-!- The enzyme also produces the cyclization product hopan-22-ol by addition of water (cf. EC 4.2.1.129). -!- Hopene and hopanol are formed at a constant ratio of 5:1.

| 4.2.1.129 |
Squalene--hopanol cyclase.
based on mapping to UniProt P33247
Hopan-22-ol = squalene + H(2)O.
-!- The enzyme produces the cyclization products hopene (cf. EC 5.4.99.17) and hopanol from squalene at a constant ratio of 5:1.
