PETase Structure

3D Model

PETase is an enzyme produced by bacterium called Ideonella sakaiensis to break down polyethylene terephthalate (PET) to use as a energy source. PET is a widely used polymere that is a major contributor to global pollution. Understanding the strucutre of PETase and how it works is vital as knowing the structure will allow for the use of biotechnology to optimise PETase and prevent more pollution from PET and other polymers. This is a mutated form of wild-type PETase to show the ligand in the activesite.
