zeaxanthin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = antheraxanthin + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O
generic compounds
: zeaxanthin epoxidase first step of two-step reaction (see R10070, R06946+R06947)
: A flavoprotein (FAD) that is active under conditions of low light. Along with EC 1.10.99.3, violaxanthin de-epoxidase, this enzyme forms part of the xanthophyll (or violaxanthin) cycle, which is involved in protecting the plant against damage by excess light. It will also epoxidize lutein in some higher-plant species.
