EC 1.14.15.14

Accepted name: methyl-branched lipid ω-hydroxylase

Reaction: a methyl-branched lipid + O2 + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ = an ω-hydroxy-methyl-branched lipid + H2O + 2 oxidized ferredoxin [iron-sulfur] cluster

Other name(s): CYP124

Systematic name: methyl-branched lipid,reduced-ferredoxin:oxygen oxidoreductase (ω-hydroxylating)

Comments: The enzyme, found in pathogenic and nonpathogenic mycobacteria species, actinomycetes, and some proteobacteria, hydroxylates the ω-carbon of a number of methyl-branched lipids, including (2E,6E)-farnesol, phytanate, geranylgeraniol, 15-methylpalmitate and (2E,6E)-farnesyl diphosphate. It is a P-450 heme-thiolate enzyme.
