Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (PubMed:18658138, PubMed:20729325). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (PubMed:18658138, PubMed:20729325, PubMed:21594592, PubMed:21751386, PubMed:23603671, PubMed:25545638). Also hydrolyzes the triglyceride triolein (PubMed:18658138, PubMed:20729325, PubMed:21751386) (Probable). Capable of degrading the plastic poly(ethylene terephthalate) (PET), the most abundant polyester plastic in the world (PubMed:21751386, PubMed:25545638). a butanoate ester + H2O = an aliphatic alcohol + butanoate + H(+) (ethylene terephthalate)(n) + H2O = (ethylene terephthalate)(n-1) + 4-[(2-hydroxyethoxy)carbonyl]benzoate + H(+) cutin + H2O = cutin monomers. Activated by magnesium ions (PubMed:25545638). Activated by calcium ions (PubMed:25545638). Inhibited by the serine hydrolase inhibitor phenylmethanesulfonyl fluoride (PMSF) (PubMed:18658138). kcat is 220 sec(-1) with pNP-butanoate as substrate (PubMed:20729325). kcat is 304 sec(-1) with pNP-butanoate as substrate (at 20 degrees Celsius and pH 8) (PubMed:23603671). Optimum pH is 8. Optimum temperature is 60 degrees Celsius. May have promising applications in chemical and textile industries as it is capable of hydrolyzing a variety of substrates including soluble esters and insoluble triglycerides (PubMed:18658138, PubMed:20729325). Can hydrolyze and thus modulate the surface properties of natural fibers such as cotton (PubMed:20729325). Has potential for application in biological recycling of plastic waste products (PubMed:21751386, PubMed:25545638). As the hydrolysis reaction is reversible, may also have applications in the food industry for synthesizing short-chain aliphatic esters, odor chemicals used as food flavorings (PubMed:27041308). Belongs to the AB hydrolase superfamily.
