We examined the effects of air-water and water-sevoflurane interfaces on conformational properties of amyloid- β peptide (ABP). Fractions were extracted from sub-interfacial (air-water) and supra-interfacial (water-sevoflurane) layers and compared with aqueous bulk layers using fluorescence properties of ABP provided by a single tyrosine. The observations suggest that interfacial ABP may be more disordered than bulk ABP.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
