Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (PubMed:18658138). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (PubMed:18658138, PubMed:25545638). Also hydrolyzes the triglyceride triolein (PubMed:18658138). Capable of degrading the plastic poly(ethylene terephthalate) (PET), the most abundant polyester plastic in the world (PubMed:25545638). a butanoate ester + H2O = an aliphatic alcohol + butanoate + H(+) cutin + H2O = cutin monomers. (ethylene terephthalate)(n) + H2O = (ethylene terephthalate)(n-1) + 4-[(2-hydroxyethoxy)carbonyl]benzoate + H(+) Activated by magnesium ions (PubMed:25545638). Activated by calcium ions (PubMed:25545638). Inhibited by the serine hydrolase inhibitor phenylmethanesulfonyl fluoride (PMSF) (PubMed:18658138). Optimum pH is 8. Optimum temperature is 60 degrees Celsius. Has potential for application in biological recycling of plastic waste products. Belongs to the AB hydrolase superfamily.
