Catalyzes the hydrolysis of complex carboxylic polyesters found in the cell wall of plants (PubMed:16844780). Degrades cutin, a macromolecule that forms the structure of the plant cuticle (By similarity). Also degrades suberin, a specialized macromolecule found in the cell wall of various plant tissues (By similarity). cutin + H2O = cutin monomers. Constitutively expressed in a manner dependent on transcription factor FarB: levels are unaffected by varying lipidic or non-lipidic carbon source, or by oxidative stress. Belongs to the cutinase family.
