carotenoid beta-ring:acceptor oxidoreductase/methyltranferase (chi-ring forming)

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.
