A study of the protein-protein interactions in the phycocyanin monomer from Synechocystis sp. PCC 6803 using a bacterial two-hybrid system.

ABSTRACT: Investigations into the intramolecular interactions of the native protein in solution are important to understand its structural stability as well as its potential uses in future applications. In this study, we used a bacterial two-hybrid system to investigate the interaction between the phycocyanin α and β subunits that form the phycocyanin monomer. Key amino acid residues responsible for the interaction between the subunits were identified, providing direct experimental evidence for the intramolecular interaction.
