  2. Denaturation (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Denaturation_(biochemistry)

    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. [3]

  3. Equilibrium unfolding - Wikipedia

    en.wikipedia.org/wiki/Equilibrium_unfolding

    Equilibrium unfolding. In biochemistry, equilibrium unfolding is the process of unfolding a protein or RNA molecule by gradually changing its environment, such as by changing the temperature or pressure, pH, adding chemical denaturants, or applying force as with an atomic force microscope tip. [1][2] If the equilibrium was maintained at all ...

  4. Southern blot - Wikipedia

    en.wikipedia.org/wiki/Southern_blot

    Southern blot is a method used for detection and quantification of a specific DNA sequence in DNA samples. This method is used in molecular biology. Briefly, purified DNA from a biological sample (such as blood or tissue) is digested with restriction enzymes, and the resulting DNA fragments are separated by electrophoresis using an electric ...

  5. Enzyme - Wikipedia

    en.wikipedia.org/wiki/Enzyme

    Enzyme denaturation is normally linked to temperatures above a species' normal level; as a result, enzymes from bacteria living in volcanic environments such as hot springs are prized by industrial users for their ability to function at high temperatures, allowing enzyme-catalysed reactions to be operated at a very high rate.

  6. Protein engineering - Wikipedia

    en.wikipedia.org/wiki/Protein_engineering

    Protein engineering. Protein engineering is the process of developing useful or valuable proteins through the design and production of unnatural polypeptides, often by altering amino acid sequences found in nature. [1] It is a young discipline, with much research taking place into the understanding of protein folding and recognition for protein ...

  7. Denaturation - Wikipedia

    en.wikipedia.org/wiki/Denaturation

    Denaturation (biochemistry), a structural change in macromolecules caused by extreme conditions. Denaturation (fissile materials), transforming fissile materials so that they cannot be used in nuclear weapons. Denaturation (food), intentional adulteration of food or drink rendering it unfit for consumption while remaining suitable for other uses.

  8. Active site - Wikipedia

    en.wikipedia.org/wiki/Active_site

    In biology and biochemistry, the active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction. The active site consists of amino acid residues that form temporary bonds with the substrate, the binding site, and residues that catalyse a reaction of that substrate, the catalytic site.

  9. Denaturation mapping - Wikipedia

    en.wikipedia.org/wiki/Denaturation_mapping

    Denaturation Mapping is a form of optical mapping, first described in 1966. It is used to characterize DNA molecules without the need for amplification or sequencing. It is based on the differences between the melting temperatures of AT-rich and GC-rich regions. [1] Even though modern sequencing methods reduced the need for denaturation mapping ...
