Protein attributes

Sequence length	248 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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.
Catalytic activity	(3Z)-phycocyanobilin + oxidized ferredoxin = biliverdin IX-alpha + reduced ferredoxin.
Sequence similarities	Belongs to the HY2 family.
