Enhancing PET Degrading Enzymes: A Combinatory Approach
Problem
Plastic PET waste accumulates as a major environmental issue, and natural PET-degrading enzymes need improved efficiency for enzymatic recycling.
Why it matters
Enzymatic depolymerization could enable a circular plastic-waste economy and reduce environmental harm.
What the AI did
Machine learning was combined with structure-based rational design and ancestral sequence reconstruction to engineer a more active Combi-PETase variant.
Results
Combi-PETase variant with melting temperature of 70 °C and optimal performance at 60 °C
Impact
Produced a more active, thermostable PETase variant, per the abstract.
