Hydrophobic interaction is the main driver of protein folding. The phenomenon of hydrophobic groups gathering close to each other to avoid water is called hydrophobic interaction. The protein is stable in water when the hydrophobic side chains of the protein aggregate inside the protein, rather than being solvated by water. Hydrophobic interactions play a major role in maintaining protein conformation because water molecules interact more strongly with each other than with other nonpolar molecules. Nonpolar side chains gather inside protein molecules to avoid water. At the same time, most polar side chains maintain contact with water on the surface of the protein. The hydrophobic properties within the molecule not only explain the accumulation of hydrophobic residues, but also explain the stability of the spiral and fold plates. | Hydrophobic interaction is the main driver of protein folding.

PETase Q182I
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 QtoI at 182 position which can be more stable in higher temperature compared with the wild type.

Hydrophobic interaction is the main driver of protein folding. The phenomenon of hydrophobic groups gathering close to each other to avoid water is called hydrophobic interaction. The protein is stable in water when the hydrophobic side chains of the protein aggregate inside the protein, rather than being solvated by water. Hydrophobic interactions play a major role in maintaining protein conformation because water molecules interact more strongly with each other than with other nonpolar molecules. Nonpolar side chains gather inside protein molecules to avoid water. At the same time, most polar side chains maintain contact with water on the surface of the protein. The hydrophobic properties within the molecule not only explain the accumulation of hydrophobic residues, but also explain the stability of the spiral and fold plates.
The thermal stability improvement result was obtained by the evaluation of I-Mutant website, and the thermal stability improvement result of -0.46912 was also obtained by the FoldX evaluation.
Functional Parameters
After mutation, Q182L and A183, F201, A240 all have a new hydrophobic interaction, which can enhance the force between residues, enhance the hydrophobicity of the protein, and stabilize the protein structure.
