... havetherefore measured the thermodynamic parameters of RNase -A in the presence of these amino acids and amino acid derivatives, and values of DGD°, measured in triplicate, are given in Table ... DGD° values in the presence of these osmolytes are given in Table 1. How-ever, DGD° values of RNase -A in the presence of alanine, serine, lysine, b-alanine, taurine and dimethyl-glycine have ... significant advances in understanding the effect of osmolytes on protein stability, folding and the activity of proteins and enzymes, the relationship between protein stabilization by osmolytes and...
