In enzymology, a phytochromobilin:ferredoxin oxidoreductase (EC 1.3.7.4) is an enzyme that catalyzes the chemical reaction

(3Z)-phytochromobilin + oxidized ferredoxin biliverdin IXalpha + reduced ferredoxin

Thus, the two substrates of this enzyme are (3Z)-phytochromobilin and oxidized ferredoxin, whereas its two products are biliverdin IXalpha and reduced ferredoxin.

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.
