Enzyme Information

1.11.2.4
Fatty-acid peroxygenase.
based on mapping to UniProt O31440
Fatty acid + H(2)O(2) = 3- or 2-hydroxy fatty acid + H(2)O.
-!- A cytosolic heme-thiolate protein with sequence homology to P450 monooxygenases. -!- Unlike the latter, it needs neither NAD(P)H, dioxygen nor specific reductases for function. -!- Enzymes of this type are produced by bacteria (e.g. Sphingomonas paucimobilis, Bacillus subtilis). -!- Catalytic turnover rates are high compared with those of monooxygenation reactions as well as peroxide shunt reactions catalyzed by the common P450s. -!- A model substrate is myristate, but other saturated and unsaturated fatty acids are also hydroxylated. -!- Oxidizes the peroxidase substrate 3,3,5,5-tetramethylbenzidine (TMB) and peroxygenates aromatic substrates in a fatty-acid-dependent reaction.
