Compound as reactive (3)
2 a reduced ferredoxin [iron-sulfur] cluster + 2 H+ + oxygen + canthaxanthin → 2 an oxidized ferredoxin [iron-sulfur] cluster + H2O + adonirubin
NADH + H+ + oxygen + canthaxanthin → H2O + NAD+ + 2-hydroxycanthaxanthin
2 oxygen + 4 a reduced ferredoxin [iron-sulfur] cluster + 4 H+ + canthaxanthin → 2 H2O + 4 an oxidized ferredoxin [iron-sulfur] cluster + (3S,3'S)-astaxanthin
Compound as product (5)
4',4'-dihydroxyechinenone → H2O + canthaxanthin
3,4,3',4'-tetradehydroisozeaxanthin → canthaxanthin
2 a reduced electron donor + 2 oxygen + echinenone → 2 an oxidized electron donor + 3 H2O + canthaxanthin
a reduced electron donor + oxygen + echinenone → 2 H+ + an oxidized electron donor + H2O + canthaxanthin
an oxidized electron donor + 4'-hydroxyechinenone → a reduced electron donor + canthaxanthin
Reversible reaction (1)
2 NADH + 2 H+ + 2 oxygen + canthaxanthin ↔ 2 H2O + 2 NAD+ + 2,2'-dihydroxycanthaxanthin
