Catalyzes the hydrolysis of complex carboxylic polyesters found in the cell wall of plants (By similarity). Degrades cutin, a macromolecule that forms the structure of the plant cuticle (By similarity). cutin + H2O = cutin monomers. Weakly inhibited by n-undecyl phosphonate (C11Y4) (By similarity). Activity unaffected by paraoxon (By similarity). In contract to classical cutinases, possesses a lid formed by two N-terminal helices which covers its active site (By similarity). The lid opens in the presence of surfactants to uncover the catalytic crevice, allowing enzyme activity and inhibition (By similarity). Belongs to the cutinase family.
