| Official Name |
|---|
| Phytochromobilin:ferredoxin oxidoreductase.
|
| Alternative Name(s) |
|---|
| P-Phi-B synthase. |
| PFB synthase. |
| Phytochromobilin synthase. |
| Reaction catalysed |
|---|
| (3Z)-phytochromobilin + oxidized ferredoxin <=> biliverdin IX-alpha + reduced ferredoxin |
| Comment(s) |
|---|
- Catalyzes the two-electron reduction of biliverdin IX-alpha.
- Can use 2Fe-2S ferredoxins from a number of sources as acceptor but
not the 4Fe-4S ferredoxin from Clostridium pasteurianum.
- The isomerization of (3Z)-phytochromobilin to (3E)-phytochromobilin
is thought to occur prior to covalent attachment to apophytochrome in
the plant cell cytoplasm.
- Flavodoxins can be used instead of ferredoxin.
