Abstract

Leupeptin, a tripeptide inhibitor of some proteinases, was shown previously to maintain the stability of several enzymes (isocitrate lyase, fumarase, and catalase) in crude extracts of castor bean endosperm. This reagent is now shown to inhibit the breakdown of water-soluble and crystalloidstorage proteins of the protein bodies isolated from castor beans by the SH-proteinase and it also inhibits the endopeptidase from mung beans. When suitably introduced into the endosperm of dry castor beans it strongly inhibits germination and seedling development. Application of leupeptin to endosperm halves removed from the seed prevents the normal development of enzymes concerned with gluconeogenesis from fat and drastically curtails sugar production. The results suggest that the SH-proteinase is intimately involved in the mobilization of storage proteins.

摘要

亮抑蛋白酶肽是某些蛋白酶的三肽抑制剂，先前已证明它能维持蓖麻籽胚乳粗提物中几种酶（异柠檬酸裂解酶、延胡索酸酶和过氧化氢酶）的稳定性。现在发现该试剂可抑制蓖麻籽中分离出的蛋白体的水溶性和晶体贮藏蛋白被巯基蛋白酶分解，并且它还能抑制绿豆中的内肽酶。当将亮抑蛋白酶肽适当地导入干燥蓖麻籽的胚乳中时，它会强烈抑制发芽和幼苗发育。将亮抑蛋白酶肽应用于从种子中取出的半胚乳，可阻止与脂肪糖异生有关的酶的正常发育，并大幅减少糖分产生。结果表明，巯基蛋白酶与贮藏蛋白的动员密切相关。
