PETase S223P

The PETase is an enzyme, which can hydrolyze PET and this mutation protein is changed on the basis of the PETase. This protein is changed from S to P at 223 position which can be more stable in higher temperature compared with the wild type.

This mutant undergoes proline substitution. Proline has a special ring structure, which can increase the rigidity of the loop, reduce the conformational entropy, and improve the thermal stability of the protein.

Maestro website evaluated an result of -1.214，IMUTANT website evaluated a decrease result of -0.32, and an evaluation of FoldX also obtained a thermal stability improvement result of -0.47 kcal/mol. And the result was not ideal.
