• PubMed Abstract: 
  

  Lactococcal oligopeptide-binding protein A (OppA) binds peptides with widely varied lengths and sequences. We previously hypothesized that a hydrophobic pocket in OppA preferentially binds a hydrophobic peptide side chain and thus determines its binding register. Two crystal structures of OppA with different nonapeptides now indeed show binding in different registers.
