Characterization of Potential Plastic-Degradation Enzymes from Marine Bacteria.

ABSTRACT: Polyethylene terephthalate (PET) and polyethylene (PE) are prominent polymer materials that comprise a significant portion of commercial plastic waste. Their durability and slow degradation rate have resulted in significant accumulation of plastic on Earth. In a recent study, macrotranscriptomic profiling of a reconstituted marine bacterial community identified 10 putative enzymes capable of directly acting on PE or PET (PEases or PETases). Among these enzymes, three recombinant proteins were reported to possess PE degradation activity. To select potential plastic degrading enzyme candidates for protein engineering efforts, we expressed and purified eight out of the 10 candidates, excluding two due to poor expression and/or solubility. Notably, several candidate proteins displayed signific
