In enzymology a phycocyanobilin:ferredoxin oxidoreductase (PcyA EC 1.3.7.5) is an enzyme that catalyzes the chemical reaction(3Z)-phycocyanobilin + oxidized ferredoxin biliverdin IXalpha + reduced ferredoxinThus the two substrates of this enzyme are (3Z)-phycocyanobilin 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.
