Zeaksantin 7,8-dioksigenaza (EC 1.14.99.42, dioksigenaza razdvajanja zeaksantina 7,8(7',8'), CsZCD) je enzim sa sistematskim imenom zeaksantin:kiseonik oksidoreduktaza (7,8-razgradnja).[1] Ovaj enzim katalizuje sledeću hemijsku reakciju
- zeaksantin + 2 O2 krocetin dialdehid + 2 (3S)-3-hidroksiciklocitral
Ovaj enzim deluje dva puta na zeaksantin odvajajući 3-hidroksiciklocitral sa svake od 3-hidroksi krajnjih grupa.
