-phytochromobilin.svg)
The two substrates of this enzyme are biliverdin and reduced ferredoxin. Its products are (3Z)-phytochromobilin and oxidized ferredoxin.[1][2][3][4]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-CH group of donor with an iron-sulfur protein as acceptor. The systematic name of this enzyme class is (3Z)-phytochromobilin:ferredoxin oxidoreductase. Other names in common use include HY2, PPhiB synthase, and phytochromobilin synthase. This enzyme participates in porphyrin and chlorophyll metabolism.
