Catalyzes the hydrolysis of complex carboxylic polyesters found in the cell wall of plants (PubMed:19201950, PubMed:19739639). Degrades cutin, a macromolecule that forms the structure of the plant cuticle (PubMed:19201950). Also degrades suberin, a specialized macromolecule found in the cell wall of various plant tissues (PubMed:19201950, PubMed:19739639). cutin + H2O = cutin monomers. Optimum pH is 7-8. 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. The mass corresponds to protein with a C-terminal six histidine tag and two disulfide bridges. Belongs to the cutinase family.
