| Comments |
Catalyses the two-electron reduction of biliverdin IX¦Á. 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. |

(3Z)-phytochromobilin + 2 oxidized [2Fe-2S] ferredoxin = biliverdin IX-alpha + 2 reduced [2Fe-2S] ferredoxin. |
