"Breakthrough: Artificial Protein Degrades Microplastics in Bottles"

Scientists have developed artificial proteins capable of degrading PET microplastics and nanoplastics found in bottles. By adding three amino acids to a defense protein from the strawberry anemone, the researchers were able to create a protein that acts as scissors, cutting small PET particles. The engineered protein demonstrated an efficiency 5 to 10 times higher than existing PETases on the market, and it can operate at room temperature, reducing CO2 emissions. The protein's pore-like structure allows water to pass through, making it suitable for use in filters for purification plants. Additionally, two variants of the protein were designed, one for thorough degradation and the other for recycling, offering flexibility in its applications.
