Protein name

RecName: Full=Phycocyanobilin:ferredoxin oxidoreductase; EC=1.3.7.5;

Gene name

pcyA

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 (By similarity).

CATALYTIC ACTIVITY: (3Z)-phycocyanobilin + oxidized ferredoxin = biliverdin IX-alpha + reduced ferredoxin.

SIMILARITY: Belongs to the HY2 family.

Pfam	PF05996; Fe_bilin_red; 1;
