peptide. Here we present a conformationalstudy of c-[T-K-P-R-G] based on NMR data in a cryoprotective DMSO/water mixture. The preferred conformation is a type VIa turn centered on the K-P residues. The orientation of the side chains of the two basic residues (K and R) may represent the essential feature of the bioactive conformation of tuftsin. A possible role of tuftsin as a DNA binding motif is suggested
