Plasma kallikrein/KLKB1 蛋白, Human (HEK293, His, solution)

Plasma kallikrein (KLKB1) serves as an enzyme, cleaving Lys-Arg and Arg-Ser bonds to release bradykinin from HMW kininogen. It plays a crucial role in the reciprocal activation of factor XII, especially upon binding to a negatively charged surface. Besides its role in the kinin system, KLKB1 may contribute to the renin-angiotensin system by converting prorenin into renin. Plasma kallikrein/KLKB1 Protein, Human (HEK293, His, solution) is the recombinant human-derived Plasma kallikrein/KLKB1 protein, expressed by HEK293 , with C-His labeled tag. The total length of Plasma kallikrein/KLKB1 Protein, Human (HEK293, His, solution) is 619 a.a., with molecular weight of 72-80 kDa.

血浆激肽释放酶 (KLKB1) 是一种能够裂解 Lys-Arg 和 Arg-Ser 键的酶，有助于从 HMW 激肽原中释放缓激肽。此外，KLKB1 在通过交互反应激活因子 XII 中发挥着关键作用，特别是在其与带负电的表面结合后。除了参与激肽系统之外，这种酶还可能通过将肾素原转化为肾素来促进肾素-血管紧张素系统。
