title: Conformations of P2 protein of peripheral nerve myelin by nuclear magnetic resonance spectroscopy.
abstract: High-resolution 1H NMR spectra of P2 protein from bovine peripheral nerve myelin indicate that the protein contains a high degree of tertiary structure in aqueous solution. Denaturation of the protein in urea solutions is a multi-step process. Binding of lysophosphatidylcholine micelles to the protein causes a conformational change and a broadening of NMR peaks from side chains of aromatic amino acid and methionine residues, with much less effect on upfield methyl resonances.
