... 2005) doi:10.1111/j.1742-4658.2005.04814.x Staphylococcal nuclease (SNase) is a model protein that contains one domain and no disulfide bonds. Its stability in the native state may be maintained mainly by key amino acids. In this ... two point-mutated proteins each with a single base substitution [alanine for tryptophan (W14 0A) and alanine for lysine (K13 3A) ] and two truncated fragm...

... wild-type SNase and 20 glycine mutants suggest that the negatively charged aspartic acid and glutamic acid residues in the protein play unequal roles in main- taining the protein’s native structure. ... stability. Two local stable areas formed by the charge–charge interactions around E75 and E129 with particular positively charged amino acids are thus iden- tified as being significant in...
