IntEnz Enzyme Nomenclature
EC 1.3.99.37

Names

Accepted name:
1-hydroxy-2-isopentenylcarotenoid 3,4-desaturase
Other name:
crtD (gene name)
Systematic name:
dihydroisopentenyldehydrorhodopin:acceptor 3,4-oxidoreductase

Reactions

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.
