  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.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
