UniProt functional annotation for P07122

UniProt code: P07122.

Organism: Microchaete diplosiphon (Fremyella diplosiphon).
Taxonomy: Bacteria; Cyanobacteria; Nostocales; Rivulariaceae; Microchaete.
 
Function: Light-harvesting photosynthetic bile pigment-protein from the phycobiliprotein complex (phycobilisome, PBS). Phycocyanin is the major phycobiliprotein in the PBS rod.
 
Subunit: Heterodimer of an alpha and a beta subunit, which further assembles into trimers and the trimers into hexamers. {ECO:0000269|PubMed:1899708}.
Subcellular location: Cellular thylakoid membrane; Peripheral membrane protein; Cytoplasmic side. Note=Part of the phycobilisome rod.
Induction: Phycocyanin-1 is expressed at similar levels in green and red light (constitutive phycocyanin).
Ptm: Contains one covalently linked bilin chromophore. {ECO:0000269|PubMed:1899708, ECO:0007744|PDB:1CPC}.
Similarity: Belongs to the phycobiliprotein family. {ECO:0000305}.
