Properties of extremely thermostable proteases from anaerobic hyperthermophilic bacteria

Hyperthermostable proteases were characterized from five archaeobacterial species (Thermococcus celer, T. stetteri, Thermococcus strain AN 1, T. litoralis, Staphylothermus marinus) and the hyperthermophilic eubacterium Thermobacteroides proteolyticus. These proteases, which were found to be of the serine type, exhibited a preference for phenylalanine in the… CONTINUE READING
