Comments The enzyme, isolated from the archaeon Haloarcula japonica, is involved in the biosynthesis of the C50 carotenoid bacterioruberin. In this pathway it catalyses the desaturation of the C-3,4 double bond in dihydroisopentenyldehydrorhodopin and the desaturation of the C-3′-4′ double bond in dihydrobisanhydrobacterioruberin.
Cofactor
History
Reactions (1) Dihydroisopentenyldehydrorhodopin + acceptor = isopentenyldehydrorhodopin + reduced acceptor. (2) Dihydrobisanhydrobacterioruberin + acceptor = bisanhydrobacterioruberin + reduced acceptor.
