Detection and characterisation of a new metallocarboxypeptidase inhibitor from Solanum tuberosum cv. Desirèe using proteomic techniques

► A new potato carboxypeptidase inhibitor was isolated using proteomics techniques. ► Intensity fading is interactomic technique useful to the detection of inhibitors. ► The PCI was characterised by electrophoretic and proteomics techniques. ► Protease inhibitors could have anticarcinogenic and positive dietary effects.
