Enzyme Commission Number
EC 1.14.15.21
Product Overview
High-quality enzyme products.
Well-established quality management system.
Reaction
zeaxanthin + 4 reduced ferredoxin [iron-sulfur] cluster + 4 H+ + 2 O2 = violaxanthin + 4 oxidized ferredoxin [iron-sulfur] cluster + 2 H2O (overall reaction)
(1a) zeaxanthin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = antheraxanthin + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O
(1b) antheraxanthin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H+ + O2 = violaxanthin + 2 oxidized ferredoxin [iron-sulfur] cluster + H2O
Systematic Name
zeaxanthin,reduced ferredoxin:oxygen oxidoreductase
Function
A flavoprotein (FAD) that is active under conditions of low light. Along with EC 1.23.5.1, 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.
