CC   -!- FUNCTION: Light-harvesting photosynthetic bile pigment-protein from the
CC       phycobiliprotein complex. Allophycocyanin has a maximum absorption at
CC       approximately 650 to 653 nanometers. {ECO:0000305}.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta chain. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC       {ECO:0000250}. Note=Forms the core of the phycobilisome. {ECO:0000250}.
CC   -!- PTM: Contains one covalently linked phycocyanobilin chromophore.
CC       {ECO:0000250|UniProtKB:P00318}.
CC   -!- SIMILARITY: Belongs to the phycobiliprotein family. {ECO:0000255}.
