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 isoinhibitor components.
