 ALOX15B may also conduct this metaboism.The other enzyme attack point forms a 5,6-epoxide which is resolved to either 5,6-dihydroxy-eicosatetraenoate or 5-hydroxy eicosatetraenoate products; this step catalyzed by 5-lipoxygenase (ALOX5).Accordingly, these double oxygenations yield either 5,6,15-trihydroxy- or 5,14,15-trihydroxy-eicosatetraenoates.
