Function and Biology Details

Reactions catalysed: 
A methyl-branched lipid + O(2) + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H(+) = an omega-hydroxy-methyl-branched lipid + H(2)O + 2 oxidized ferredoxin [iron-sulfur] cluster
(1a) cholest-4-en-3-one + 2 reduced [2Fe-2S] ferredoxin + O(2) = (25R)-26-hydroxycholest-4-en-3-one + 2 oxidized [2Fe-2S] ferredoxin + H(2)O
