EC 1.3.99.37 Details
show Brenda entryEC number
1.3.99.37
Accepted name
1-hydroxy-2-isopentenylcarotenoid 3,4-desaturase
Reaction
(1) dihydroisopentenyldehydrorhodopin + acceptor = isopentenyldehydrorhodopin + reduced acceptor;; (2) dihydrobisanhydrobacterioruberin + acceptor = bisanhydrobacterioruberin + reduced acceptor
Other name(s)
crtD (gene name)
Systematic name
dihydroisopentenyldehydrorhodopin:acceptor 3,4-oxidoreductase
Comment
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.
