recombinant enzyme lacks hydroperoxide isomerase activity, but shows low epoxyalcohol synthase activity with biosynthesis of a novel oxylipin, 12S(13R)-epoxy-(10R)-hydroxy-18:1. The enzyme oxygenates 20:4n-6 (all-cis-5,8,11,14-eicosatetraenoic acid) i.e. by hydrogen abstraction at both C-13 and C-10 with formation of two nonconjugated and four cis-trans-conjugated hydroperoxyeicosatetraenoic acid
