  ABSTRACT  
 
Pex13p is an essential component of the peroxisomal protein import machinery and interacts via its C-terminal SH3 domain with the type II SH3-ligand Pex14p and the non-PXXP protein Pex5p. We report the solution structure of the SH3 domain of Pex13p from Saccharomyces cerevisiae and the identification of a novel-binding pocket, which binds a non-PXXP-peptide representing the binding site of Pex5p. Chemical shift assays revealed the binding sites for Pex5p and Pex14p ligand peptides to be distinct and spatially separated. Competition assays demonstrated that the two ligand peptides can bind simultaneously to the SH3 domain.

Figure 2. Identification of the SH3-binding fragments of Pex5p and Pex14p. (A) Two hybrid interactions of Pex13p[aa285-386] and various fragments of ScPex5p. Interactions were analyzed by the b-galactosidase filter assay. (B) Cellulose membranes decorated with 26-mer peptides covering amino acid residues 181-312 of ScPex5p with one-amino acid shifts between neighboring peptides and (C) 12-mer peptides covering the entire protein sequence of ScPex14p with three-amino acid shifts between neighboring peptides were incubated with the recombinant GST-tagged SH3 domain of ScPex13p. Peptide-SH3complexes were identified by the peptide spot overlay assay using antibodies against GST.

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 code is shown on the right.
