Default Pilin C-terminal peptide binds asialo-GM1 in liposomes: a 2H-NMR study.

Pilin C-terminal peptide binds asialo-GM1 in liposomes: a 2H-NMR study.

Related Articles Pilin C-terminal peptide binds asialo-GM1 in liposomes: a 2H-NMR study.

Protein Sci. 1997 Nov;6(11):2459-61

Authors: Jones DH, Hodges RS, Barber KR, Grant CW

Wideline 2H-NMR observations are described demonstrating the interaction of a synthetic peptide (PAK), representing residues 128-144 of the binding domain of pilin surface protein from Pseudomonas aeruginosa, with a complex glycosphingolipid thought to be its natural receptor. The receptor glycolipid (asialo-GM1) carried 2H probe nuclei on the terminal and next-to-terminal carbohydrate residues and was present as a minor component in fluid phosphatidylcholine liposomes. The peptide induced spectral changes that could be understood as arising from receptor motional changes, without receptor immobilization on the NMR time scale of 10(4) s-1. Spectral effects were reversed by reduction of the single peptide disulfide bond--a structural feature previously shown to be a determinant of PAK conformation (Campbell AP, McInnes C, Hodges RS, Sykes BD. 1995. Biochemistry 34:16255-16268). This is the first demonstration of PAK interaction with its epithelial cell receptor in liposomes.
