General annotation (Comments)

Function

Plays a role in phycoerythrobilin biosynthesis, the red pigment chromophore photosynthetically active biliproteins of the host cyanobacteria. Uses a four-electron reduction to carry out the reactions catalyzed by two enzymes (EC 1.3.7.2 and EC 1.3.7.3) in host.

Catalytic activity

(3Z)-phycoerythrobilin + 2 oxidized ferredoxin = biliverdin IX-alpha + 2 reduced ferredoxin. Ref.2

Sequence similarities

Belongs to the HY2 family.
