Glucuronoyl esterase – Novel carbohydrate esterase produced by Schizophyllum commune [PDF]

open access: yesFEBS Letters, 2006
The cellulolytic system of the wood‐rotting fungus Schizophyllum commune contains an esterase that hydrolyzes methyl ester of 4‐O‐methyl‐d‐glucuronic acid. The enzyme, called glucuronoyl esterase, was purified to electrophoretic homogeneity from a cellulose‐spent culture fluid.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...
