PETase S142P

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 142 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. Using FoldX and I-Mutant to predict the stability of S142P, it was found that the stability decreased, and the result was not ideal.
