PETase N173R

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 N to R at 173 position which can be more stable in higher temperature compared with the wild type.

Adding hydrogen bonds stabilized α4-β6loop The reduction of DDG was predicted by FoldX. PyOML was used for visual screening, which formed hydrogen bonds with 169-SER and 176-LEU. after mutation to ARG, he formed new hydrogen bonds with 172-ASN, which stabilized α4-β6loop and was beneficial to improve the thermal stability of PETase.
