ENZYME entry: EC 1.3.7.6

Accepted Name
Phycoerythrobilin synthase.
Reaction catalysed
(3Z)-phycoerythrobilin + 2 oxidized ferredoxin <=> biliverdin IX-alpha + 2 reduced ferredoxin
Comment(s)
  • 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 1.3.7.2 and EC 1.3.7.3.
  • 15,16-dihydrobiliverdin is formed as a bound intermediate.
  • Free 15,16-dihydrobiliverdin can also act as a substrate to form phycoerythrobilin.
