| Abstract: | Abstract One of the most thermostable and thermoactive enzymes ever described has been characterized from a hyperthermophilic archaebacterium Pyrococcus furiosus . The enzyme system of this bacterium was capable of hydrolyzing starch forming a mixture of various oligosaccharides. Unlike the amylases from aerobic bacteria this enzyme does not require metal ions for activity or stability. The enzyme is catalytically active over a very broad temperature range, namely between 40°C and 140°C. The half life of this peculiar enzyme during autoclaving at 120°C is 2 h. |
