Protein
Phycoerythrobilin synthase
Organism
Prochlorococcus phage P-SSM2
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.
Similarity
Belongs to the HY2 family.
