Reaction: ALOX5 dehydrogenates 7(S)-Hp-17(S)-HDHA to 7S(8)-epoxy-17S-HDHA

- in pathway: Biosynthesis of D-series resolvins
5-lipoxygenase (ALOX5) possesses dual lipoxygenase activity (Shimizu et al. 1984). In polymorphonuclear (PMN) cells, ALOX5 can epoxygenate (via dehydration) 7(S)-hydroperoxy-17(S)-hydroxydocosahexaenoic acid (7(S)-Hp-17(S)-HDHA) to form 7S(8)-epoxy-17(S)-hydroxydocosahexaenoic acid (7S(8)-epoxy-17(S)-HDHA (Serhan et al. 2002).
