Effect of salts on C-phycocyanin.
Abstract The effect of a number of inorganic anions on the quaternary structure of C-phycocyanin has been investigated by fluorescence polarization. Dissociation to monomer occurred in the order: SCN − > ClO 4 − > NO 3 − > Br − > Cl − . These results suggest that hydrophobic interactions are important in the hexamer-monomer equilibrium of C-phycocyanin.
