Bacteriol. 189:4534-4538(2007). CC -!- FUNCTION: Functions as a fatty acid monooxygenase. Catalyzes CC hydroxylation of a range of medium to long-chain fatty acids, with CC a preference for long-chain unsaturated and branched-chain fatty CC acids over saturated fatty acids. Hydroxylation of myristic acid CC occurs mainly at the omega-2 and omega-3 positions, in CC approximately equal proportions. Also displays a NADPH-dependent CC reductase activity in the C-terminal domain, which allows electron CC transfer from NADPH to the heme iron of the cytochrome P450 N- CC terminal domain. {ECO:0000269|PubMed:14741768, CC ECO:0000269|PubMed:15122913}. CC -!- CATALYTIC ACTIVITY: RH + [reduced NADPH--hemoprotein reductase] + CC O(2) = ROH + [oxidized NADPH--hemoprotein reductase] + H(2)O. CC {ECO:0000269|PubMed:14741768, ECO:0000269|PubMed:15122913}. CC -!- CATALYTIC ACTIVITY: NADPH + n oxidized hemoprotein = NADP(+) + n CC reduced hemoprotein. {ECO:0000269|PubMed:14741768, CC ECO:0000269|PubMed:15122913}.

CC -!- INDUCTION: Negatively regulated by the transcriptional repressor CC FatR (PubMed:11574077, PubMed:11734890). Is induced by fatty acids CC such as oleate, linoleate and phytanate, that bind and displace CC the FatR repressor (PubMed:11734890). Is also induced by CC palmitate, likely via another mechanism (PubMed:11574077). CC Transcribed under partial control of SigM ECF sigma factor CC (PubMed:17434969). {ECO:0000269|PubMed:11574077, CC ECO:0000269|PubMed:11734890, ECO:0000269|PubMed:17434969}.
