Enzyme Information
| 1.3.7.6 |
Phycoerythrobilin synthase.
based on mapping to UniProt Q58MU6
(3Z)-phycoerythrobilin + 2 oxidized ferredoxin = biliverdin IX-alpha + 2 reduced ferredoxin.
-!- This enzyme, from a cyanophage infecting oceanic cyanobacteria of the Prochlorococcus genus, uses a four-electron reduction to carry out the reactions catalyzed by EC 1.3.7.2 and EC 1.3.7.3. -!- 15,16-dihydrobiliverdin is formed as a bound intermediate. -!- Free 15,16-dihydrobiliverdin can also act as a substrate to form phycoerythrobilin.
