‘Molecular scissors’ for plastic waste

A research team has solved the molecular structure of the enzyme MHETase at BESSY II. MHETase was discovered in bacteria and together with a second enzyme — PETase — is able to break down the widely used plastic PET into its basic building blocks. This 3D structure already allowed the researchers to produce a MHETase variant with optimized activity in order to use it, together with PETase, for a sustainable recycling of PET.
