They are composed of at least two dissimilar polypeptides, α and β subunits, in a molar ratio of 1:1. The subunits possess linear tetrapyrrole prosthetic groups covalently linked to the primary structure via cysteine thioether linkages. In blue-green and red algae, phycobiliproteins occur in a supramolecular structure, the phycobilisome, located on the surface of thylakoid to展开更多

The results revealed 44.4% of nucleotidesequence similarity and 30.4% of similarity of deduced amino acid sequence between them. The aminoacid sequence identities between S. maxima and S. platensis are 99 .4% for α subunit and 100% for βsubunit.展开更多
A new model is proposed to study the interaactions among chromphores in APC trimer. Using this model, the electronic transition frequencies are calculated. The results are in good agreement with the experimental.
