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