Spheroidene monooxygenase (EC 1.14.15.9, CrtA, acyclic carotenoid 2-ketolase, spirilloxantin monooxygenase, 2-oxo-spirilloxanthin monooxygenase) is an enzyme with systematic name spheroidene, reduced-ferredoxin:oxygen oxidoreductase (spheroiden-2-one-forming). This enzyme catalyses the following chemical reaction
spheroidene + reduced ferredoxin + O2
⇌
{\displaystyle \rightleftharpoons }
spheroiden-2-one + oxidized ferredoxin + H2O
spirilloxantin + reduced ferredoxin + O2
⇌
{\displaystyle \rightleftharpoons }
2-oxospirilloxanthin + oxidized ferredoxin + H2O
2'-oxospirilloxanthin + reduced ferredoxin + O2
⇌
{\displaystyle \rightleftharpoons }
2,2'-dioxospirilloxanthin + oxidized ferredoxin + H2O
The enzyme is involved in spheroidenone biosynthesis and in 2,2'-dioxospirilloxanthin biosynthesis.
