Catalyzes the hydrolysis of complex carboxylic polyesters found in the cell wall of plants (PubMed:18987860). May degrade cutin, a macromolecule that forms the structure of the plant cuticle (PubMed:18987860). May also degrade suberin, a specialized macromolecule found in the cell wall of various plant tissues (PubMed:18987860). cutin + H2O = cutin monomers. Optimum pH is 7.5-8. Induced during growth on olive oil (PubMed:18987860). Induced during growth on the lipidic carbon source 16-hydroxyhexadecanoic acid (synthetic cutin monomer) (PubMed:18987860). Induced during growth on plant material (PubMed:18987860). Induced during growth on pectin (PubMed:18987860). Repressed during growth on glucose carbon source (PubMed:18987860). 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. Belongs to the cutinase family.
