WebCys to Ala mutations in this context would be considered non-conservative. The disulfide bond that least affects stability encloses the smallest sequence loop. Given the data, treatment of the wildtype enzyme with beta-mercaptoethanol would likely shift the Tm to the right. Previous question Next question A conservative replacement (also called a conservative mutation or a conservative substitution) is an amino acid replacement in a protein that changes a given amino acid to a different amino acid with similar biochemical properties (e.g. charge, hydrophobicity and size). Conversely, a radical replacement, or radical substitution, is an amino acid replacement that exchanges an initial amino acid by a final amino acid with different physicochemical properties. rockland webradio live
