Researchers at The Australian National University (ANU) have developed a method to enhance the efficiency of plastic-degrading enzymes by modifying a single atom. This breakthrough allows the enzyme to degrade polyethylene terephthalate (PET) at nearly double its normal rate without losing thermal stability, addressing a significant challenge in plastic waste management.
The importance of this research lies in its potential to significantly impact the 350 million tons of PET plastic waste generated globally each year. By utilizing synthetic, non-canonical amino acids, the ANU team has managed to improve the catalytic activity of PETases while maintaining their structural integrity, a feat that has been difficult to achieve in enzyme engineering.
Looking ahead, the focus will be on further refining this technique and exploring its commercial viability. The study indicates that precise atomic modifications can lead to substantial improvements in enzyme performance, which could pave the way for more effective solutions to the ongoing plastic pollution crisis. No further timeline was disclosed at the time of publication.
