IUBMB Comments

Catalyses the two-electron reduction of biliverdin IXα. 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.

The expected taxonomic range for this enzyme is: Eukaryota, Bacteria

Synonyms
aurea, phytochromobilin synthase, zmhy2, cshy2, pphib synthase, 3z-phytochromobilin:ferredoxin oxidoreductase, more
