Abstract
Provided herein is a thermolabile proteinase and methods of using the same. In some embodiments, the thermolabile proteinase may comprise an amino acid sequence that is at least 90% identical to any of SEQ ID NOs:1-11 and at least one amino acid substitution in helix 3. The thermolabile proteinase is active at a temperature in the range of 4° C.-40° C. and is inactivated by raising the temperature to above 50° C., where the proteinase is substantially inactive at 65° C.
