In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Glucansucrase (also known as glucosyltransferase) is an enzyme in the glycoside hydrolase family GH70 used by lactic acid bacteria to split sucrose; it then utilizes the resulting glucose molecules to build long, sticky biofilm chains. These extracellular homopolysaccharides are called α-glucan polymers.
Capsaicin acts as an antifungal agent in four primary ways. First, capsaicin inhibits the metabolic rate of the cells that make up the fungal biofilm. [81] This inhibits the area and growth rate of the fungus, since the biofilm creates an area where a fungus can grow and adhere to the chili in which capsaicin is present. [82]
In humans, the C-type lysozyme enzyme is encoded by the LYZ gene. [3] [4] Hen egg white lysozyme is thermally stable, with a melting point reaching up to 72 °C at pH 5.0. [5] However, lysozyme in human milk loses activity very quickly at that temperature. [6] Hen egg white lysozyme maintains its activity in a large range of pH (6–9). [7]
T. aquaticus is a bacterium that lives in hot springs and hydrothermal vents, and Taq polymerase was identified [1] as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR. [2] Therefore, it replaced the DNA polymerase from E. coli originally used in PCR. [3]
Thermus aquaticus is a species of bacteria that can tolerate high temperatures, one of several thermophilic bacteria that belong to the Deinococcota phylum. It is the source of the heat-resistant enzyme Taq DNA polymerase, one of the most important enzymes in molecular biology because of its use in the polymerase chain reaction (PCR) DNA amplification technique.
Clothes made of delicate materials such as wool and silk can be damaged in high-temperature washes, and jeans and denim can fade due to their dark dyes. Low-temperature washes with detergent enzymes can prevent this damage, meaning that consumers can buy clothes from a wider range of materials without worrying about damaging them during washing ...
Denaturation midpoint of a protein is defined as the temperature (T m) or concentration of denaturant (C m) at which both the folded and unfolded states are equally populated at equilibrium (assuming two-state protein folding). T m is often determined using a thermal shift assay.
