Template:Infobox enzyme Zeaxanthin 7,8-dioxygenase (Template:EC number, zeaxanthin 7,8(7',8')-cleavage dioxygenase, CsZCD) is an enzyme with systematic name zeaxanthin:oxygen oxidoreductase (7,8-cleaving).[1] This enzyme catalyses the following chemical reaction
- zeaxanthin + 2 O2 crocetin dialdehyde + 2 (3S)-3-hydroxycyclocitral
Zeaxanthin 7,8-dioxygenase acts twice on zeaxanthin cleaving 3-hydroxycyclocitral off each 3-hydroxy end group.
