Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (Ref.4, PubMed:31690819, PubMed:24728714, PubMed:23604968). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (Ref.4, PubMed:31690819, PubMed:24728714, PubMed:23604968, PubMed:15638529, PubMed:25545638). Also hydrolyzes the triglycerides triacetin, tributyrin, tricaprin, and trilaurin, with a preference for short-chain substrates (PubMed:15638529). Hydrolyzes the hemicellulose xylan (PubMed:20816933). Capable of degrading the plastic poly(ethylene terephthalate) (PET), the most abundant polyester plastic in the world (Ref.4, PubMed:25545638, PubMed:31690819, PubMed:32269349). Can also depolymerize poly(epsilon-caprolactone) (PCL), a synthetic aliphatic biodegradable polyester (PubMed:15638529). Hydrolyzes polyoxyethylenesorbate esters with a preference for shorter chain lengths (PubMed:20816933). H2O + pentanoate ester = an aliphatic alcohol + H(+) + pentanoate an octanoate ester + H2O = an aliphatic alcohol + H(+) + octanoate decanoate ester + H2O = an aliphatic alcohol + decanoate + H(+) a dodecanoate ester + H2O = an aliphatic alcohol + dodecanoate + H(+) a tetradecanoate ester + H2O = an aliphatic alcohol + H(+) + tetradecanoate H2O + hexadecanoate ester = an aliphatic alcohol + H(+) + hexadecanoate cutin + H2O = cutin monomers. an acetyl ester + H2O = acetate + an aliphatic alcohol + H(+) (ethylene terephthalate)(n) + H2O = (ethylene terephthalate)(n-1) + 4-[(2-hydroxyethoxy)carbonyl]benzoate + H(+) a butanoate ester + H2O = an aliphatic alcohol + butanoate + H(+) Activated by magnesium ions (PubMed:25545638). Activated by calcium ions (PubMed:25545638). Inhibited by the serine hydrolase inhibitor phenylmethanesulfonyl fluoride (PMSF) (Probable). kcat is 39.5 sec(-1) with pNP-acetate as substrate (at 25 degrees Celsius and pH 7) (Ref.4). kcat is 253 sec(-1) with pNP-butanoate as substrate (at 50 degrees Celsius and pH 8) (PubMed:23604968). kcat is 30.9 sec(-1) with pNP-butanoate as substrate (at 25 degrees Celsius and pH 7) (Ref.4). Optimum pH is 8 (PubMed:23604968). Optimum pH is 6.0-6.5 (PubMed:15638529). Optimum pH is 7.5 (PubMed:20816933). Optimum temperature is 25-50 degrees Celsius (PubMed:24728714). Optimum temperature is 55 degrees Celsius (PubMed:23604968). Optimum temperature is 60 degrees Celsius (PubMed:20816933). Optimum temperature is 65 degrees Celsius (PubMed:15638529, PubMed:31690819, PubMed:32269349). Monomer. Has potential for application in biological recycling of plastic waste products (Ref.4, PubMed:25545638, PubMed:31690819, PubMed:32269349). Shows promising applications in the laundry industry as a cleansing agent, as it is thermostable and tolerant to surfactants and organic solvents (PubMed:23604968). Also shows promising applications in ethyl alcohol distillery processes as it may be utilized for treatment of molasses wastewater (PubMed:33387709). Belongs to the AB hydrolase superfamily.
