Protein
Mono(2-hydroxyethyl) terephthalate hydrolase
Organism
Ideonella sakaiensis (strain 201-F6)
Function
Involved in the degradation and assimilation of the plastic poly(ethylene terephthalate) (PET), which allows I.sakaiensis to use PET as its major energy and carbon source for growth. Likely acts synergistically with PETase to depolymerize PET. Catalyzes the hydrolysis of mono(2-hydroxyethyl) terephthalate into its two environmentally benign monomers, terephthalate and ethylene glycol. Does not show activity against PET, bis(hydroxyethyl) terephthalate (BHET), pNP-aliphatic esters or typical aromatic ester compounds catalyzed by the tannase family enzymes, such as ethyl gallate and ethyl ferulate.
Similarity
Belongs to the tannase family.
