Heat-loving archaea enzyme. Colour transmission electron micrograph (TEM) showing a heat-resistant enzyme complex from the hyperthermophile (high temperature-loving) archaea Staphylothermus marinus. Enzymes bring molecules together to produce chemical reactions needed for life. This enzyme or extremozyme is called "stalk-associated archaebacterial endoprotease" (STABLE) and has potential use in industry since it can function at up to 135 degrees Celsius. S. marinus is an extremophile, surviving extreme temperatures of up to 98 degrees Celsius, in deep ocean hydrothermal vents. Magnification: x38,000 at 6x6cm size.
