| Sysname |
(3Z)-phycoerythrobilin:ferredoxin oxidoreductase |
|---|
| Reaction(IUBMB) |
(3Z)-phycoerythrobilin + oxidized ferredoxin =
15,16-dihydrobiliverdin + reduced ferredoxin [RN:R05819] |
|---|
| Reaction(KEGG) |
R05819
 |

| 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. |
