  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. Thermus aquaticus - Wikipedia

    en.wikipedia.org/wiki/Thermus_aquaticus

    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.

  4. Taq polymerase - Wikipedia

    en.wikipedia.org/wiki/Taq_polymerase

    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]

  5. Heat shock response - Wikipedia

    en.wikipedia.org/wiki/Heat_shock_response

    The heat shock response (HSR) is a cell stress response that increases the number of molecular chaperones to combat the negative effects on proteins caused by stressors such as increased temperatures, oxidative stress, and heavy metals. [1]

  6. Thermostable DNA polymerase - Wikipedia

    en.wikipedia.org/wiki/Thermostable_DNA_Polymerase

    Similar effects are also achieved with mixtures of thermostable DNA polymerases of both types with a mixing ratio of the enzyme activities of type A and B polymerases of 30 to 1, [22] [36] e.g. Herculase [8] and TaqPlus [10] as a commercial mixture of Taq and Pfu polymerase, Expand as a commercial mixture of Taq and Pwo, [37] Expand High ...

    The search for missing hiker Susan Lane-Fournier, 61, took a tragic turn after her body was found over the weekend in Welches, Oregon, an unincorporated community at the base of Mount Hood.

  8. Hyperthermophile - Wikipedia

    en.wikipedia.org/wiki/Hyperthermophile

    At certain points of the membrane, side chains linked by covalent bonds and a monolayer are found at these points. Thus, the membrane is much more stable and resistant to temperature alterations than the acidic bilayers present in eukaryotic organisms and bacteria. Proteins: denature at elevated temperatures and so also must adapt. Protein ...

    After meeting in a bar in Texas, I asked my now-wife, Cecilia, if she'd fly to Australia to see me. I couldn't believe it when she said yes.
