Name
1-hydroxy-2-isopentenylcarotenoid 3,4-desaturase;
crtD (gene name)
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With unknown physiological acceptors
BRITE hierarchy
Sysname
dihydroisopentenyldehydrorhodopin:acceptor 3,4-oxidoreductase
Reaction(IUBMB)
(1) dihydroisopentenyldehydrorhodopin + acceptor = isopentenyldehydrorhodopin + reduced acceptor [RN:
R12708 ];
(2) dihydrobisanhydrobacterioruberin + acceptor = bisanhydrobacterioruberin + reduced acceptor [RN:
R12709 ]
Reaction(KEGG)
Substrate
dihydroisopentenyldehydrorhodopin [CPD:
C22058 ];
acceptor [CPD:
C00028 ];
dihydrobisanhydrobacterioruberin [CPD:
C22060 ]
Product
isopentenyldehydrorhodopin [CPD:
C22059 ];
reduced acceptor [CPD:
C00030 ];
bisanhydrobacterioruberin [CPD:
C22347 ]
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.
