WebApr 14, 2024 · The purity of the protein was estimated by SDS-PAGE (calculated molecular mass of SynDLP: 93 kDa) and the protein was typically ≥95% pure. Per liter E. coli culture, 1–2 mg protein was purified. WebThe net stability of a protein is quite marginal. All three features, the hydrophobic effect, van der Waals, and H-bonds are required to overcome the very favorable change in conformational entropy when a protein unfolds. This delicate balance is illustrated in the following diagram.

WebDec 13, 2010 · Instead the marginal stability is the result of a balance between predominantly destabilizing mutations and selection that shifts depending on effective population size. Even if marginal stability is not an adaptation, the natural tendency of proteins toward marginal stability, and the range of stabilities that occur during evolution, … WebAbstract Most globular proteins are marginally stable regardless of size or activity. The most common interpretation is that proteins must be marginally stable in order to function, and so marginal stability represents the results of positive selection. We consider ...

WebNov 2, 2024 · As is well known for proteins, during evolution, temperature-adaptive changes in sequence foster retention of optimal marginal stability at a species’ normal physiological temperatures. Here, we extend this type of analysis to messenger RNAs (mRNAs), a class of macromolecules for which the stability–lability balance has not been elucidated. WebWe find that the marginal stability of proteins is an inherent property of proteins due to the high dimensionality of the sequence space, without regard to protein function.
