摘要：

A papain inhibitor of 22 kDa was isolated from human placenta and shown to be identical to residues Cys246-Leu373 of the third domain of human kininogen. This kininogen domain and recombinant human cystatin C were inactivated by peptide bond cleavages at hydrophobic amino acid residues due to the action of cathepsin D. These results further support the proposed role of cathepsin D in the regulation of cysteine proteinase activity.
