Abstract

Three protein proteolytic enzyme inhibitors with molecular masses 21,22, and 23 kDa have been isolated from intact potato tubers (Solanum tuberosum L. cv, Istrinskii). The 21 and 22 kDa proteins denoted as PSPI-21 and PSPI-22, respectively, are serine proteinase inhibitors withdifferent specificity. The 23 kDa protein denoted as PCPI-23 is an inhibitor of plant cysteine proteinases, The PSPI-21 molecule consists of two disulfide-linked polypeptide chains with molecular masses of 16.5 kDa and 4.5 kDa, The PSPI-22 and PCPI-23 hale one polypeptide chain,Their amino-termini numbered 21-25 amino acid residues have significant homology to other plant inhibitors which are members of the soybeanKunitz inhibitor family, It is found that at least PSPI-21 and PSPI-22 can predominantly accumulate in potato tubers infected with Phytophthora infestans zoospores, (C) 1998 Federation of European Biochemical Societies.
