'''Phycocyanobilin:ferredoxin oxidoreductase''' (PcyA) is a member of the Fd-dependent bilin family. PcyA reduces vinyl groups of biliverdin IX-α to yield phycocyanobilin<ref>PMID:15250720</ref>. Phycocyanobilin is a pigment precursor of the light-harvesting antennae in red algae and cyanobacteria. | '''Phycocyanobilin:ferredoxin oxidoreductase''' (PcyA) is a member of the Fd-dependent bilin family.
