DT   01-NOV-1997, sequence version 1.
DT   03-AUG-2022, entry version 78.
DE   RecName: Full=C-phycocyanin-2 alpha subunit;
GN   Name=cpcA2;
OS   Pseudanabaena tenuis (strain PCC 7409).
OC   Bacteria; Cyanobacteria; Pseudanabaenales; Pseudanabaenaceae;
OC   Pseudanabaena.
OX   NCBI_TaxID=29415;
RN   [1]
RP   NUCLEOTIDE SEQUENCE [GENOMIC DNA].
RA   Dubbs J.M., Bryant D.A.;
RT   "Organization and transcription of the genes encoding two differentially
RT   expressed phycocyanins in the cyanobacterium Pseudanabaena sp. PCC 7409.";
RL   Submitted (AUG-1992) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Light-harvesting photosynthetic bile pigment-protein from the
CC       phycobiliprotein complex (phycobilisome, PBS). Phycocyanin is the major
CC       phycobiliprotein in the PBS rod.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta subunit, which further
CC       assembles into trimers and the trimers into hexamers.
CC       {ECO:0000250|UniProtKB:P13530}.
CC   -!- SUBCELLULAR LOCATION: Cellular thylakoid membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}; Cytoplasmic side
CC       {ECO:0000250}. Note=Part of the phycobilisome rod. {ECO:0000250}.
CC   -!- PTM: Contains one covalently linked bilin chromophore. {ECO:0000250,
CC       ECO:0000250|UniProtKB:P13530}.
CC   -!- SIMILARITY: Belongs to the phycobiliprotein family. {ECO:0000305}.
