Immunological similarities of proteinase inhibitors from potatoes.
Proteinase inhibitors, purified independently from Japanese, United States, and German potato varieties, and having different physicochemical and inhibitory properties, are shown to be immunochemically similar. These results indicate that the heterogeneity found among proteinase inhibitors from potato tubers is apparently due both to intervarietal, as well as intravarietal, variations in isoinh...
متن کاملImmunological Identification of Proteinase Inhibitors I and II in Isolated Tomato Leaf Vacuoles.
Proteinase inhibitor I has been identified and quantified in isolated vacuoles from tomato (Lycopersicon esculentum) leaves induced to accumulate inhibitors either by wounding or by supplying excised leaves with the wound hormone, proteinase inhibitor-inducing factor. Proteinase inhibitor II was also identified in the vacuoles but not quantified. Control vacuoles were prepared from unwounded pl...
متن کاملPartial purification of proteinase inhibitors from wounded tomato plants.
Proteinase inhibitors were extracted from the upper leaves of tomato plants, Lycopersicon esculentum Mill., 48 hours after wounding single lower leaves. Inhibitors were partially purified by affinity chromatography and isoelectric focusing. Significantly higher levels of trypsin and chymotrypsin inhibitory activity were recovered from wounded plants than from unwounded controls. Several inhibit...
متن کاملProteinase inhibitors in rheumatoid arthritis.
The concentrations of five normally occurring protease inhibitors in serum and synovial fluid were compared in patients with rheumatoid arthritis, osteoarthrosis, and normal controls. The patients with rheumatoid arthritis showed a significant rise in alpha1-antitrypsin, alpha1-antichymotrypsin, and inter-alpha-trypsin inhibitor (in decreasing order) in serum as well as in synovial fluid. In sy...
متن کاملProteinase inhibitors in rat serum
Three different serine proteinase inhibitors were isolated from rat serum and purified to apparent homogeneity. One of the inhibitors appears to be homologous to a1-proteinase inhibitor isolated from man and other species, but the other two, designated rat proteinase inhibitor I and rat proteinase inhibitor II, seem to have no human counterpart. ac-Proteinase inhibitor (Mr 55000) inhibits tryps...
