oxygen + (6Z,9Z,12Z,15Z,18Z,21Z)-tetracosahexaenoyl-CoA → (2E,6Z,9Z,12Z,15Z,18Z,21Z)-tetracosaheptaenoyl-CoA + hydrogen peroxide
H+ + (1R,6R)-1,4,5,5a,6,9-hexahydrophenazine-1,6-dicarboxylate + oxygen → hydrogen peroxide + (1R,10aS)-1,4,10,10a-tetrahydrophenazine-1-carboxylate + CO2
(1R,6R)-1,4,5,5a,6,9-hexahydrophenazine-1,6-dicarboxylate + oxygen → hydrogen peroxide + (1R,10aS)-1,4,10,10a-tetrahydrophenazine-1,6-dicarboxylate
