Abstract

Abstract : Raman and NMR spectroscopy together with DFT quantum chemical calculations have been used to elucidate conformational changes occurring during inverse temperature transition in water solution of two elastin‒like polypentapeptides, poly(G1 V1 G2 V2 P) and poly(AV1 GV2 P). From the temperature dependences of Raman spectra and 1 H– 1 H NOESY spectra follows that above the transition temperature a β (II)‒turn conformational structure is formed on the residue located between Pro and Val1 .
