• PubMed Abstract: 
  

  Here we present the high-resolution NMR structure of a chimera (SPCp41) between alpha-spectrin SH3 domain and the decapeptide p41. The tertiary structure mimics perfectly the interactions typically found in SH3-peptide complexes and is remarkably similar to that of the complex between the separate Spc-SH3 domain and ligand p41. Relaxation data confirm the tight binding between the ligand and SH3 part of the chimera. This chimera will serve as a tool for a deeper understanding of the relationship between structure and thermodynamics of binding using a combination of NMR, stability and site-directed mutagenesis studies, which can lead to an effective strategy for ligand design.
