PETase L43C&K252C

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 L43C&K252C which can be more stable in higher temperature compared with the wild type.

Disulfide bonds are introduced near the N-terminal to stabilize the n-terminal alpha helix.

During Pymol visual examination, it was found that the mutation site was far away from the inside of the protein, which met the disulfide bond geometric standard, but destroyed the existing salt bridge (E44-K252). DDG is 0.663kcal/mol evaluated by FoldX.
