KEGG   ENZYME: 1.3.99.40
Entry
EC 1.3.99.40                Enzyme                                 
Name
carotenoid chi-ring synthase;
crtU (gene name) (ambiguous);
cruE (gene name)
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With unknown physiological acceptors
Sysname
carotenoid beta-ring:acceptor oxidoreductase/methyltranferase (chi-ring-forming)
Reaction(IUBMB)
carotenoid beta-end group + 2 acceptor = carotenoid chi-end group + 2 reduced acceptor [RN:R12116]
Reaction(KEGG)
R12116 > R07849
Substrate
carotenoid beta-end group [CPD:C21915];
acceptor [CPD:C00028]
Product
carotenoid chi-end group [CPD:C21917];
reduced acceptor [CPD:C00030]
Comment
The enzyme, found in purple sulfur bacteria (Chromatiaceae) and some cyanobacteria, is involved in the biosynthesis of carotenoids that contain chi-type end groups, such as okenone, renierapurpurin, and synechoxanthin.
