The biochemical properties of heretofore uncharacterized extracellular proteases of rat interleukin-2-activated natural killer (A-NK) cells were investigated. Following p-aminobenzamidine- and D-phenylalanine-agarose affinity chromatography both trypsin- and chymotrypsin-like protease activities were found. Zymography revealed "trypsin-like" activities, with apparent molecular weights of approximately 42 kDa to 20.5 kDa, and "chymotrypsin-like" activities of approximately 27 kDa, to 22 kDa. These proteases might contribute to diverse NK cell functions, and the characteristics of these proteolytic activities are compared with those of granzymes of lytic granules and the proteasome of A-NK cells.
