In enzymology, a phycoerythrobilin:ferredoxin oxidoreductase (EC 1.3.7.3) is an enzyme that catalyzes the chemical reaction
(3Z)-phycoerythrobilin + oxidized ferredoxin
⇌
{\displaystyle \rightleftharpoons }
15,16-dihydrobiliverdin + reduced ferredoxin
Thus, the two substrates of this enzyme are (3Z)-phycoerythrobilin and oxidized ferredoxin, whereas its two products are 15,16-dihydrobiliverdin 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)-phycoerythrobilin:ferredoxin oxidoreductase. This enzyme is also called PebB. This enzyme participates in porphyrin and chlorophyll metabolism.
