Template:Short description Template:Infobox enzyme Zeaxanthin epoxidase (Template:EC number, Zea-epoxidase) is an enzyme with systematic name zeaxanthin,NAD(P)H:oxygen oxidoreductase.[1][2][3][4][5][6][7] This enzyme catalyses the following chemical reaction
- zeaxanthin + 2 NAD(P)H + 2 H+ + 2 O2 violaxanthin + 2 NAD(P)+ + 2 H2O (overall reaction)
- (1a) zeaxanthin + NAD(P)H + H+ + O2 antheraxanthin + NAD(P)+ + H2O
- (1b) antheraxanthin + NAD(P)H + H+ + O2 violaxanthin + NAD(P)+ + H2O
Zeaxanthin epoxidase is a flavoprotein (FAD) that is active under conditions of low light.
