FUNCTION | Catalyzes the four-electron reduction of biliverdin IX-alpha (2-electron reduction at both the A and D rings); the reaction proceeds via an isolatable 2-electron intermediate, 181,182-dihydrobiliverdin. |
CATALYTIC ACTIVITY | Reaction=(2R,3Z)-phycocyanobilin + 4 oxidized [2Fe-2S]-[ferredoxin] = biliverdin IXalpha + 4 H(+) + 4 reduced [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:15309, Rhea:RHEA-COMP:10000, Rhea:RHEA-COMP:10001, ChEBI:CHEBI:15378, ChEBI:CHEBI:33737, ChEBI:CHEBI:33738, ChEBI:CHEBI:57437, ChEBI:CHEBI:57991; EC=1.3.7.5; |
SIMILARITY | Belongs to the HY2 family. |
