Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (PubMed:34705546). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (PubMed:34705546). Can depolymerize synthetic polyesters such as poly(epsilon-caprolactone) (PCL) and poly(1,3-propylene adipate) (PPA) (PubMed:34705546). Exhibits some activity on poly(lactic acid) (PLA) (PubMed:34705546). Can bind but not hydrolyze poly(hydroxybutyrate) (PHB) (PubMed:34705546). cutin + H2O = cutin monomers. a tetradecanoate ester + H2O = an aliphatic alcohol + H(+) + tetradecanoate H2O + hexadecanoate ester = an aliphatic alcohol + H(+) + hexadecanoate a butanoate ester + H2O = an aliphatic alcohol + butanoate + H(+) an octanoate ester + H2O = an aliphatic alcohol + H(+) + octanoate Optimum pH is 8. Shows promising applications in improving the surface properties of natural textile fibers. Belongs to the cutinase family.
