Plastics, especially polyethylene terephthalate (PET), are vital in modern life, with global production exceeding 400 million tons annually. This extensive use has led to significant plastic waste pollution, highlighting the need for effective recycling strategies. PET, one of the most recycled plastics, is a prime candidate for degradation into its original monomers through engineered PET hydrolases - enzymes with industrial potential. While previous engineering efforts have mainly focused on enhancing thermostability and catalytic efficiency, the crucial aspect of enzyme adsorption to PET surfaces has received less attention. This review specifically addresses the mechanisms of enzyme adsorption, detailing relevant experimental methods and simulation techniques while emphasizing the potential for engineering more effective PET hydrolases.

Lysosomal Hydrolases
Hydrolysis
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...
