In enzymology, a phycocyanobilin:ferredoxin oxidoreductase (PcyA, EC 1.3.7.5) is an enzyme that catalyzes the chemical reaction
(3Z)-phycocyanobilin + oxidized 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. The systematic name of this enzyme class is (3Z)-phycocyanobilin:ferredoxin oxidoreductase. This enzyme participates in porphyrin and chlorophyll metabolism.
Structural studies
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 2D1E, 2DKE, and 2G18.
