[[http://www.uniprot.org/uniprot/CPXB_BACME CPXB_BACME]] Functions as a fatty acid monooxygenase. Catalyzes hydroxylation of medium and long-chain fatty acids at omega-1, omega-2 and omega-3 positions, with optimum chain lengths of 12-16 carbons (lauric, myristic, and palmitic acids). The reductase domain is required for electron transfer from NADP to cytochrome P450.  
[https://www.uniprot.org/uniprot/CPXB_PRIM2 CPXB_PRIM2] Functions as a fatty acid monooxygenase (PubMed:3106359, PubMed:1727637, PubMed:16566047, PubMed:7578081, PubMed:11695892, PubMed:14653735, PubMed:16403573, PubMed:18004886, PubMed:17077084, PubMed:17868686, PubMed:18298086, PubMed:18619466, PubMed:18721129, PubMed:19492389, PubMed:20180779, PubMed:21110374, PubMed:21875028). Catalyzes hydroxylation of fatty acids at omega-1, omega-2 and omega-3 positions (PubMed:1727637, PubMed:21875028). Shows activity toward medium and long-chain fatty acids, with optimum chain lengths of 12, 14 and 16 carbons (lauric, myristic, and palmitic acids). Able to metabolize some of these primary metabolites to secondary and tertiary products (PubMed:1727637). Marginal activity towards short chain lengths of 8-10 carbons (PubMed:1727637, PubMed:18619466). Hydroxylates highly branched fatty acids, which play an essential role in membrane fluidity regulation (PubMed:16566047). Also displays a NADPH-dependent reductase activity in the C-terminal domain, which allows electron transfer from NADPH to the heme iron of the cytochrome P450 N-terminal domain (PubMed:3106359, PubMed:1727637, PubMed:16566047, PubMed:7578081, PubMed:11695892, PubMed:14653735, PubMed:16403573, PubMed:18004886, PubMed:17077084, PubMed:17868686, PubMed:18298086, PubMed:18619466, PubMed:18721129, PubMed:19492389, PubMed:20180779, PubMed:21110374, PubMed:21875028). Involved in inactivation of quorum sensing signals of other competing bacteria by oxidazing efficiently acyl homoserine lactones (AHLs), molecules involved in quorum sensing signaling pathways, and their lactonolysis products acyl homoserines (AHs) (PubMed:18020460).<ref>PMID:11695892</ref> <ref>PMID:14653735</ref> <ref>PMID:16403573</ref> <ref>PMID:16566047</ref> <ref>PMID:17077084</ref> <ref>PMID:1727637</ref> <ref>PMID:17868686</ref> <ref>PMID:18004886</ref> <ref>PMID:18020460</ref> <ref>PMID:18298086</ref> <ref>PMID:18619466</ref> <ref>PMID:18721129</ref> <ref>PMID:19492389</ref> <ref>PMID:20180779</ref> <ref>PMID:21110374</ref> <ref>PMID:21875028</ref> <ref>PMID:3106359</ref> <ref>PMID:7578081</ref>
