Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (PubMed:25910960). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (PubMed:25910960). Capable of degrading the plastic poly(ethylene terephthalate) (PET), the most abundant polyester plastic in the world (PubMed:25910960). Can also depolymerize the synthetic polyester poly(epsilon-caprolactone) (PCL) (PubMed:25910960). (ethylene terephthalate)(n) + H2O = (ethylene terephthalate)(n-1) + 4-[(2-hydroxyethoxy)carbonyl]benzoate + H(+) a butanoate ester + H2O = an aliphatic alcohol + butanoate + H(+) cutin + H2O = cutin monomers. Optimum pH is 6. Optimum temperature is 50 degrees Celsius. Monomer. Expression is not induced by the synthetic polyester poly(butylene succinate-co-adipate) (PBSA). Has potential for application in biological recycling of plastic waste products. Belongs to the AB hydrolase superfamily.
