All parameters were obtained from ITC measurements at pH 7.0 and 25°C. Note that the consensus residues within the PPXY motif of each peptide are colored blue for clarity. All binding stoichiometries were fixed to unity. Errors were calculated from at least three independent measurements. All errors are given to one standard deviation.
