Heat-loving bacteria enzyme. Colour transmission electron micrograph (TEM) showing a heat- resistant enzyme complex from the hyperthermophile (high temperature-loving) bacteria 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 belongs to the Archaea group (primitive bacteria). It is an extremophile, surviving extreme temperatures of up to 98 degrees Celsius, in deep ocean hydrothermal vents.
