Potato tubers (Solanum tuberosum) secrete two kinds of proteinase inhibitors after a water stress. The polypeptides have differing inhibitory activities but are Kunitz-type inhibitors based on amino-terminal sequences homologies. A proteolysis maturation type of a cell protease inhibitor was observed. They can constitute high MW complex, sometimes with another type of protein. The function of these protease inhibitors is discussed in relation to plant defence.
马铃薯块茎（茄属马铃薯）在水分胁迫后会分泌两种蛋白酶抑制剂。这些多肽具有不同的抑制活性，但基于氨基末端序列同源性，它们属于库尼茨型抑制剂。观察到一种细胞蛋白酶抑制剂的蛋白水解成熟类型。它们可以构成高分子量复合物，有时还会与另一种蛋白质结合。本文讨论了这些蛋白酶抑制剂在植物防御方面的功能。
