[[http://www.uniprot.org/uniprot/CPXB_BACMB CPXB_BACMB]] 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).

Steroidal C7beta alcohols and their respective esters have shown significant promise as neuroprotective and anti-inflammatory agents to treat chronic neuronal damage like stroke, brain trauma and cerebral ischemia. Since position C7 is spatially far away from any functional groups that could direct C-H activation, these transformations are not readily possible using modern synthetic organic techniques. We report P450-BM3 mutants that catalyze the oxidative hydroxylation of six different steroids with pronounced C7-regio- and beta-stereoselectivity as well as high activity. These challenging transformations were achieved by a focused mutagenesis strategy and application of a novel technology for protein library construction based on DNA assembly and USER (Uracil-Specific Excision Reagent) cloning. Upscaling reactions enabled the purification of the respective steroidal alcohols in moderate to excellent yields. The high-resolution X-ray structure and molecular dynamics simulations of the best mutant unveil the origin of regio- and stereoselectivity.
