1.3.7.6 |
| Accepted name: |
phycoerythrobilin synthase |
| Reaction: |
(3Z)-phycoerythrobilin + 2 oxidized ferredoxin = biliverdin IXα + 2 reduced ferredoxin |
| Other name(s): |
PebS |
| Systematic name: |
(3Z)-phycoerythrobilin:ferredoxin oxidoreductase (from biliverdin IXα) |
| Comments: |
This enzyme, from a cyanophage infecting oceanic cyanobacteria of the Prochlorococcus genus, uses a four-electron reduction to carry out the reactions catalysed by EC 1.3.7.2 (15,16-dihydrobiliverdin:ferredoxin oxidoreductase) and EC 1.3.7.3 (phycoerythrobilin:ferredoxin oxidoreductase). 15,16-Dihydrobiliverdin is formed as a bound intermediate. Free 15,16-dihydrobiliverdin can also act as a substrate to form phycoerythrobilin. |
