The invention relates to thermal and pH stable catalases. One catalase of the invention was purified and characterized from Thermus brockianus . As a part of the characterization, the enzyme was compared to typical catalases from commercial sources and found to be significantly more thermal/alkaline stable than these other enzymes. The catalase purified from T. brockianus consists of four identical subunits having a molecular mass of approximately 42.5 kDa, for a total molecular mass of approximately 178 kDa. |
