Mapping bacterial cutinase sequence space by high-throughput screening reveals that PET hydrolysis is a rare property
Poly(ethylene terephthalate) (PET) is one of the most widely produced plastics, and enzymatic depolymerization offers a promising route to closed-loop recycling under mild conditions. However, most known bacterial PET hydrolases belong to a conserved canonical-fold cutinase family, leaving much of α/β-hydrolase diversi...
