Expression and characterization of CYP52 genes involved in the biosynthesis of sophorolipid and alkane metabolism from Starmerella bombicola.
Huang F.C., Peter A., Schwab W.
Three cytochrome P450 monooxygenase CYP52 gene family members were isolated from the sophorolipid-producing yeast Starmerella bombicola (former Candida bombicola), namely, CYP52E3, CYP52M1, and CYP52N1, and their open reading frames were cloned into the pYES2 vector for expression in Saccharomyces ... >> More
Three cytochrome P450 monooxygenase CYP52 gene family members were isolated from the sophorolipid-producing yeast Starmerella bombicola (former Candida bombicola), namely, CYP52E3, CYP52M1, and CYP52N1, and their open reading frames were cloned into the pYES2 vector for expression in Saccharomyces cerevisiae. The functions of the recombinant proteins were analyzed with a variety of alkane and fatty acid substrates using microsome proteins or a whole-cell system. CYP52M1 was found to oxidize C16 to C20 fatty acids preferentially. It converted oleic acid (C18:1) more efficiently than stearic acid (C18:0) and linoleic acid (C18:2) and much more effectively than α-linolenic acid (C18:3). No products were detected when C10 to C12 fatty acids were used as the substrates. Moreover, CYP52M1 hydroxylated fatty acids at their ω- and ω-1 positions. CYP52N1 oxidized C14 to C20 saturated and unsaturated fatty acids and preferentially oxidized palmitic acid, oleic acid, and linoleic acid. It only catalyzed ω-hydroxylation of fatty acids. Minor ω-hydroxylation activity against myristic acid, palmitic acid, palmitoleic acid, and oleic acid was shown for CYP52E3. Furthermore, the three P450s were coassayed with glucosyltransferase UGTA1. UGTA1 glycosylated all hydroxyl fatty acids generated by CYP52E3, CYP52M1, and CYP52N1. The transformation efficiency of fatty acids into glucolipids by CYP52M1/UGTA1 was much higher than those by CYP52N1/UGTA1 and CYP52E3/UGTA1. Taken together, CYP52M1 is demonstrated to be involved in the biosynthesis of sophorolipid, whereas CYP52E3 and CYP52N1 might be involved in alkane metabolism in S. bombicola but downstream of the initial oxidation steps. << Less

We have used reversed phase-high performance liquid chromatography-mass spectrometry (RP-HPLC-MS) with an ion trap mass spectrometer to study the metabolism of arachidonic and linoleic acids by human recombinant cytochrome P450 (CYP) enzymes. We first recorded the MS2 spectra of the carboxylate anions of epoxides, diols, omega-side chain, and bisallylic hydroxy fatty acids of arachidonic, octadeuterated arachidonic, and linoleic acids. The metabolites formed by CYP2C9 and CYP2C19 were then studied. CYP2C9 converted arachidonic and linoleic acids to epoxides/diols and monohydroxy fatty acids. Some hydroxyeicosatetraenoic acids (HETEs) were studied in detail to investigate the oxygenation mechanism. Incubation of CYP2C9 under oxygen-18 gas showed that all HETEs had incorporated oxygen-18 to the same degree. Chiral HPLC showed that CYP2C9 formed 15R-HETE (72% of the R enantiomer), 13S-HETE (90%), and 11R-HETE (57%). RP-HPLC-MS analysis revealed that CYP2C19 oxygenated arachidonic acid to 19-HETE, 14,15-epoxyeicosatrienoic acid (EET), and 8,9-EET as main metabolites. The method was sufficiently sensitive to identify arachidonic acid metabolites formed by some other isozymes. RP-HPLC-MS with MS2 seems to be useful for rapid identification of fatty acid metabolites in complex mixtures formed by cytochrome P450. << Less
