Outline of Final Research Achievements

For the advanced use of two novel enzymes PET hydrolase (PETase) and mono (hydroxyethyl) terephthalate (MHET) hydrolase (MHETase) found from a poly(ethylene terephthalate) (PET)-degrading bacterium, these enzymes have been functionally identified, developed for the abundant soluble protein expression, and functionally improved. As a result, detailed functions of PETase has been identified and PETase mutants with improved thermal stability has been obtained.
