Figure 3From: The high-resolution NMR structure of the R21A Spc-SH3:P41 complex: Understanding the determinants of binding affinity by comparison with Abl-SH3Stereo view of the ensemble of 20 NMR structures of the free and bound form of R21A Spc-SH3. The lowest-energy, water-refined structures of the free (blue) and bound (red) forms were superimposed on the backbone atoms (N,Ca,C') of residues 7–60.Back to article page
