However, a folded protein has an overall lower entropy. Although the amino acid sequence (also known as the protein’s primary structure) does not change, the protein’s shape may change so much that it becomes dysfunctional, in which case the protein is considered denatured. We have shown previously that drug resistant and genetic disease mutations can both act through changes in protein conformational equilibria and dynamics (3–7). A comparative study of structure, stability and function of sc-tenecteplase in the presence of stabilizing osmolytes. The prediction of changes in protein stability and structure resulting from single amino acid substitutions is both a fundamental test of macromolecular modeling methodology and an important current problem as high throughput sequencing reveals sequence polymorphisms at an increasing rate. Proteins are very sensitive to changing temperatures and a change in temperature may result in unfolding or denaturation. The quaternary structure of macromolecules is stabilized by the same non-covalent interactions and disulfide bonds as the tertiary structure, and can also be affected by formulation conditions.
