This model describes the alpha subunit of cytochrome b559, about 83 residues in length. The N-terminal half is homologous to the ~ 40-residue beta subunit. Cytochrome b559 is associated with photosystem II. Sequences scoring between trusted and noise cutoffs are fragments. [Energy metabolism, Photosynthesis]
