Abstract

A naturally occurring competitive inhibitor of pig kidney renin has been identified in human plasma. The inhibitor was shown to be alpha-1 anti-trypsin and the effect in vitro on the renin activity was examined. The slope in the Hill plot is compatible with the assumption of one-site competitive inhibition. Other proteinase inhibitors, such as alpha-2-macroglobulin and C1 inactivator, however, have no inhibitory effect on the renin-angiotensinogen reaction.

摘要

在人血浆中已鉴定出一种天然存在的猪肾肾素竞争性抑制剂。该抑制剂被证明是α-1抗胰蛋白酶,并对其体外对肾素活性的影响进行了研究。希尔图中的斜率与单位点竞争性抑制的假设相符。然而,其他蛋白酶抑制剂,如α-2-巨球蛋白和C1灭活剂,对肾素-血管紧张素原反应没有抑制作用。
