Near Complete Depolymerization Of Polyesters With Nano-Dispersed Enzymes was recently published in Nature. By nanoscopically dispersing enzymes with deep active sites, Xu, Russell and coworkers have degraded semi-crystalline polyesters primarily via chain-end mediated processive depolymerization with programmable latency and material integrity, akin to polyadenylation-induced mRNA decay.
