Experimental
alanine scanning results for PPIs (amino acid numbering
taken from PDB ID): (a) NMR structure for NOXA-B/MCL-1 (PDB ID 2JM6, model 1)), (b)
representative competition fluorescence anisotropy inhibition curves
for inhibition of the FITC–Ahx–NOXA-B/MCL-1 (50 mM Tris,
150 mM NaCl, 0.01% Triton-X, pH 7.4. using FITC–Ahx–NOXA-B
as a tracer at 25 nM concentration and MCL-1 at 200 nM concentration)
interaction using variant NOXA-B peptides, (c) NMR structure for SIMS/SUMO
(PDB ID 2LAS, model 1), (d) representative fluorescence anisotropy titration
curves for interaction of FAM labeled variant SIMS peptides with SUMO
(20 mM Tris, 150 mM NaCl, 0.01% Triton-X, pH 7.4, using 50 nM FAM–PEG–SIM
tracer), (e) crystal structure for GKAP/SHANK-PDZ (PDB ID 1Q3P), (f) representative
isothermal titration calorimetry curves for interaction of acetylated
GKAP variant peptides with SHANK-PDZ (20 mM Tris, 150 mM NaCl, pH
7.5, at 25 °C, 150 μM SHANK-PDZ).
