EC 22.214.171.124: Phycoerythrobilin synthase
(3Z)-phycoerythrobilin + 2 oxidized ferredoxin = biliverdin IX-alpha + 2 reduced ferredoxin.
- This enzyme, from a cyanophage infecting oceanic cyanobacteria of the Prochlorococcus genus, uses a four-electron reduction to carry out the reactions catalyzed by EC 126.96.36.199 and EC 188.8.131.52.
- 15,16-dihydrobiliverdin is formed as a bound intermediate.
- Free 15,16-dihydrobiliverdin can also act as a substrate to form phycoerythrobilin.
(3Z)-phycoerythrobilin:ferredoxin oxidoreductase (from biliverdin IX-alpha)
- not assigned
