RP-HPLC/MS2 analysis of oxygenation products of 18:2n-6 formed by recombinant FOXB_03425 and transformation of 10-HPODE by this enzyme. A: RP-HPLC/MS2 analysis revealed biosynthesis of 8- and 10-H(P)ODE, and 12(13)-epoxy-10-hydroxy-(8E)-octadecenoic acid (peak I) from 18:2n-6. B: The top chromatogram shows transformation of 10R-HPODE by FOXB_03425 to 12(13)-epoxy-10(R)-hydroxy-(8E)-octadecenoic acid (peak I), and the bottom chromatogram shows that 10S-HPODE was a poor substrate.
