1 The biosynthetic crossover of 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2) enzymatic activities is a productive pathway to convert arachidonic acid into unique eicosanoids. Arachidonic Acid arachidonate 5-lipoxygenase Homo sapiens
2 The biosynthetic crossover of 5-lipoxygenase (5-LOX) and cyclooxygenase-2 (COX-2) enzymatic activities is a productive pathway to convert arachidonic acid into unique eicosanoids. Arachidonic Acid arachidonate 5-lipoxygenase Homo sapiens
3 Here, we show that COX-2 catalysis with 5-LOX derived 5-hydroxy-eicosatetraenoic acid yields the endoperoxide 5-hydroxy-PGH2 that spontaneously rearranges to 5-OH-PGE2 and 5-OH-PGD2, the 5-hydroxy analogs of arachidonic acid derived PGE2 and PGD2. Arachidonic Acid arachidonate 5-lipoxygenase Homo sapiens
