Phycoerythrobilin synthase

Phycoerythrobilin synthase (, PebS) is an enzyme with systematic name (3Z)-phycoerythrobilin:ferredoxin oxidoreductase (from biliverdin IX alpha). This enzyme catalyses the following chemical reaction


 * (3Z)-phycoerythrobilin + 2 oxidized ferredoxin $$\rightleftharpoons$$ biliverdin IX alpha + 2 reduced ferredoxin

This enzyme, from a cyanophage infecting oceanic cyanobacteria of the Prochlorococcus genus.
