PETase G139R

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 G to R at 139 position which can be more stable in higher temperature compared with the wild type.

Adding hydrogen bonds stabilized α3 helix and α3-β5loop screening, which formed hydrogen bonds with 135-ALA and 136-SER. after mutating it into ARG, it formed hydrogen bonds with 151-THR, which stabilized α3 helix and α3-β5loop, which was beneficial to improve the thermal stability of PETase.
