CC   -!- FUNCTION: Catalyzes the hydrolysis of complex carboxylic polyesters
CC       found in the cell wall of plants (By similarity). Degrades cutin, a
CC       macromolecule that forms the structure of the plant cuticle (By
CC       similarity). Allows pathogenic fungi to penetrate through the cuticular
CC       barrier into the host plant during the initial stage of fungal
CC       infection (By similarity). {ECO:0000250|UniProtKB:P00590}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=cutin + H2O = cutin monomers.; EC=3.1.1.74;
CC         Evidence={ECO:0000255|PROSITE-ProRule:PRU10108, ECO:0000255|PROSITE-
CC         ProRule:PRU10109};
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P11373}.
CC   -!- PTM: The 2 disulfide bonds play a critical role in holding the
CC       catalytic residues in juxta-position; reduction of the disulfide
CC       bridges results in the complete inactivation of the enzyme.
CC       {ECO:0000250|UniProtKB:P11373}.
CC   -!- SIMILARITY: Belongs to the cutinase family. {ECO:0000305}.
