WebApr 14, 2014 · Another way in which hyperthermophiles ensure their proteins’ proper function is through the use of heat shock proteins (HSPs). These are proteins that help to keep other proteins in their proper shapes. They will often refold denatured proteins and them functional again. WebJul 7, 2010 · As a consequence of this structural flexibility, psychrophilic proteins are unstable and heat-labile. In the upper range of biological temperatures, thermophiles and hyperthermophiles grow at temperatures > 100 °C and synthesize ultra-stable proteins. However, thermophilic enzymes are nearly inactive at room temperature as a result of …
