ENZYME entry: EC 1.14.15.9

PURL: https://purl.expasy.org/enzyme/EC/1.14.15.9
Accepted Name
spheroidene monooxygenase
Alternative Name(s)
2-oxo-spirilloxanthin monooxygenase
acyclic carotenoid 2-ketolase
spirilloxanthin monooxygenase
Reaction catalysed
  • spheroidene + 4 reduced [2Fe-2S]-[ferredoxin] + 2 O2 + 4 H(+) = spheroiden-2-one + 4 oxidized [2Fe-2S]-[ferredoxin] + 3 H2O
  • spirilloxanthin + 4 reduced [2Fe-2S]-[ferredoxin] + 2 O2 + 4 H(+) = 2-oxospirilloxanthin + 4 oxidized [2Fe-2S]-[ferredoxin] + 3 H2O
  • 2-oxospirilloxanthin + 4 reduced [2Fe-2S]-[ferredoxin] + 2 O2 + 4 H(+) = 2,2'-dioxospirilloxanthin + 4 oxidized [2Fe-2S]-[ferredoxin] + 3 H2O
Comment(s)
  • The enzyme is involved in spheroidenone biosynthesis and in 2,2'-dioxospirilloxanthin biosynthesis.
  • The enzyme from Rhodobacter sphaeroides contains heme at its active site.
