General annotation (Comments)

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. HAMAP MF_00618

Catalytic activity

(3Z)-phycocyanobilin + oxidized ferredoxin = biliverdin IX-alpha + reduced ferredoxin. HAMAP MF_00618

Sequence similarities

Belongs to the HY2 family.
