| Reactions |
(1) Spheroidene + 2 reduced ferredoxin [iron-sulfur] cluster + 2 O(2) = spheroiden-2-one + 2 oxidized ferredoxin [iron-sulfur] cluster + 3 H(2)O. (2) Spirilloxanthin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 O(2) = 2-oxospirilloxanthin + 2 oxidized ferredoxin [iron-sulfur] cluster + 3 H(2)O. (3) 2-oxospirilloxanthin + 2 reduced ferredoxin [iron-sulfur] cluster + 2 O(2) = 2,2′-dioxospirilloxanthin + 2 oxidized ferredoxin [iron-sulfur] cluster + 3 H(2)O. |
