EC 184.108.40.206: 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 220.127.116.11 and EC 18.104.22.168.
- 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)
