- You have discovered a novel protein that has a pl = 5.5. To study the functional properties of this new protein, your research group has made a mutant that contains two amino acid changes: a surface phenylalanine residue in the normal protein has been replaced by histidine (side chain pK, = 6.1), and a surface glutamine has been replaced by glutamic acid (side chain pK, = 6.0). Is the pl of the mutant protein predicted to be greater than, less than, or the same as the pI of normal protein?
