Interfacial Recognition between Reconstituted Myoglobin Having Charged Binding Domain and Electron Acceptor via Electrostatic Interaction
Myoglobins reconstituted with synthetic zinc porphyrins having multiple carboxylic acid or alkylamine groups bound to the terminal of peripheral side chains can bind cationic methyl viologen or anionic hexacyanoferrate, respectively, via electrostatic interaction, where the distribution of the charged amino acid residues on the myoglobin surface has an influence on complex formation between the protein and its partner.
