ENZYME entry: EC 1.3.99.37

Accepted Name
1-hydroxy-2-isopentenylcarotenoid 3,4-desaturase.
Reaction catalysed
  • Dihydroisopentenyldehydrorhodopin + acceptor <=> isopentenyldehydrorhodopin + reduced acceptor
  • Dihydrobisanhydrobacterioruberin + acceptor <=> bisanhydrobacterioruberin + reduced acceptor
Comment(s)
  • The enzyme, isolated from the archaeon Haloarcula japonica, is involved in the biosynthesis of the C(50) carotenoid bacterioruberin.
  • In this pathway it catalyzes the desaturation of the C-3,4 double bond in dihydroisopentenyldehydrorhodopin and the desaturation of the C-3'-4' double bond in dihydrobisanhydrobacterioruberin.
