Thermostable proteins are often more useful than their non-thermostable counterparts, e.g., DNA polymerase in the polymerase chain reaction, [7] so protein engineering often includes adding mutations to increase thermal stability. Protein crystallization is more successful for proteins with a higher melting point [8] and adding buffer ...
A protein mixture is aliquoted into several tubes, which are exposed in parallel to different temperatures and a thermostable protease. The remaining protein can be resolved on SDS-PAGE . Fast parallel proteolysis ( FASTpp ) is a method to determine the thermostability of proteins by measuring which fraction of protein resists rapid proteolytic ...
Nature's Fynd (formerly known as Sustainable Bioproducts LLC and focused on biofuel) is a company that develops microbe-based proteins for meat substitutes and dairy substitutes. The protein is produced by a fungus first identified in geothermal springs in Yellowstone National Park.
Gary J. Pielak (born July 17, 1955) is an American biological chemist who is known for developing quantitative techniques for measuring protein structure, stability, diffusion, and concentration in living cells, and under crowded conditions.
For protein-protein interactions, or protein-DNA interactions FoldX calculates ∆∆G of interaction : ∆∆G ab = ∆G ab - (∆G a + ∆G b ) + ∆G kon + ∆S sc ∆G kon reflects the effect of electrostatic interactions on the k on . ∆S sc is the loss of translational and rotational entropy upon making the complex.
Using a mutated pseudo-wild-type protein specifically mutated to prevent precipitation at high pH, the salt bridge’s contribution to the overall free energy of the folded protein state can be determined by performing a point-mutation, altering and, consequently, breaking the salt bridge.

These interactions include salt bridges and hydrogen bonds. Salt bridges are unaffected by high temperatures, therefore, are necessary for protein and enzyme stability. A third force used to increase thermostability in proteins and enzymes is the presence of disulfide bonds. They present covalent cross-linkages between the polypeptide chains.
