protein, X, showed only one peptide band in native PAGE at pH 5 and 8.5. When the protein was run in SDS-PAGE, the ectrophoregram showed 2 bands of MW equal to approximately K the size of the untreated protein. What interactions are volved between the monomeric polypeptide components of otein X? A. H-bonding between cys and his B. Electrostatic interaction between lys and glu C. Disulfide bonds between cys residues O D. Covalent bond between amino acid components of the monomers E. Non-covalent interactions among the amino acids at the interface of the monomers
