| Enzyme Function | FUNCTION: 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). Allows pathogenic fungi to penetrate through the cuticular barrier into the host plant during the initial stage of fungal infection (By similarity). {ECO:0000250|UniProtKB:P00590}. |

| Modified Residue | |
| Post Translational Modification | PTM: The 2 disulfide bonds play a critical role in holding the catalytic residues in juxta-position; reduction of the disulfide bridges results in the complete inactivation of the enzyme. {ECO:0000250|UniProtKB:P11373}. |
