ID 1.17.8.1 DE hydroxysqualene dehydroxylase. CA FAD + H(+) + H2O + squalene = FADH2 + hydroxysqualene. CC -!- This enzyme, isolated from the bacteria Rhodopseudomonas palustris CC and Zymomonas mobilis, participates, along with EC 2.5.1.103 and CC EC 4.2.3.156, in the conversion of all-trans-farnesyl diphosphate to CC squalene. CC -!- Eukaryotes achieve the same goal in a single step, catalyzed by CC EC 2.5.1.21. DR Q6N3F3, HPNE_RHOPA ; P55349, HPNE_SINFN ; Q5NP65, HPNE_ZYMMO ; //
