Accepted name: phycoerythrobilin:ferredoxin oxidoreductase
Reaction: (3Z)-phycoerythrobilin + oxidized ferredoxin = 15,16-dihydrobiliverdin + reduced ferredoxin
Other name(s): PebB
Systematic name: (3Z)-phycoerythrobilin:ferredoxin oxidoreductase
Comments: Catalyses the two-electron reduction of the C2 and C31 diene system of 15,16-dihydrobiliverdin. Specific for 15,16-dihydrobiliverdin. It has been proposed that this enzyme and EC, 15,16-dihydrobiliverdin:ferredoxin oxidoreductase, function as a dual enzyme complex in the conversion of biliverdin IXα to phycoerythrobilin.
