A series of phosphotripeptide ligands for the Grb2 SH2 domain was designed and synthesized, each of which derived from the minimal consensus sequence required for binding: Ac-pYXN. The binding affinity and related thermodynamic parameters were determined by isothermal titration calorimetry. Both the size and connectivity of the side-chain was varied. The consequences of incorporating α,α-disubstitution at the pY+1 residue on binding thermodynamics were evaluated, as were the effects of constraining the side-chains in a ring. The series was evaluated from a number of perspectives: (1) increasing size of the pY+1 residue by utilizing various amino acid types: monoalkyl, dialkyl, or cycloalkyl; (2) comparisons between ligands with the same number of carbons (scission control); and (3) by comparing ligands incorporating cyclic pY+1 res...
