Entry
EC 1.3.7.3                  Enzyme                                 

Name
phycoerythrobilin:ferredoxin oxidoreductase;
PebB
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With an iron-sulfur protein as acceptor
BRITE hierarchy
Sysname
(3Z)-phycoerythrobilin:ferredoxin oxidoreductase
Reaction(IUBMB)
(3Z)-phycoerythrobilin + oxidized ferredoxin = 15,16-dihydrobiliverdin + reduced ferredoxin [RN:R05819]
Reaction(KEGG)
Substrate
(3Z)-phycoerythrobilin [CPD:C05912];
oxidized ferredoxin [CPD:C00139]
Product
15,16-dihydrobiliverdin [CPD:C11630];
reduced ferredoxin [CPD:C00138]
Comment
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 1.3.7.2, 15,16-dihydrobiliverdin:ferredoxin oxidoreductase, function as a dual enzyme complex in the conversion of biliverdin IXalpha to phycoerythrobilin.
