KEGG   ENZYME: 1.3.7.5
Entry
EC 1.3.7.5                  Enzyme                                 
Name
phycocyanobilin:ferredoxin oxidoreductase
Class
Oxidoreductases;
Acting on the CH-CH group of donors;
With an iron-sulfur protein as acceptor
Sysname
(3Z)-phycocyanobilin:ferredoxin oxidoreductase
Reaction(IUBMB)
(3Z)-phycocyanobilin + 4 oxidized ferredoxin = biliverdin IXalpha + 4 reduced ferredoxin [RN:R05817]
Reaction(KEGG)
R05817
Substrate
(3Z)-phycocyanobilin [CPD:C05786];
oxidized ferredoxin [CPD:C00139]
Product
biliverdin IXalpha;
reduced ferredoxin [CPD:C00138]
Comment
Catalyses the four-electron reduction of biliverdin IXalpha (2-electron reduction at both the A and D rings). Reaction proceeds via an isolatable 2-electron intermediate, 181,182-dihydrobiliverdin. Flavodoxins can be used instead of ferredoxin. The direct conversion of biliverdin IXalpha (BV) to (3Z)-phycocyanolbilin (PCB) in the cyanobacteria Synechocystis sp. PCC 6803, Anabaena sp. PCC7120 and Nostoc punctiforme is in contrast to the proposed pathways of PCB biosynthesis in the red alga Cyanidium caldarium, which involves (3Z)-phycoerythrobilin (PEB) as an intermediate [2] and in the green alga Mesotaenium caldariorum, in which PCB is an isolable intermediate.
