一般描述

偶氮酪蛋白是酪蛋白的显色衍生物。[1]偶氮酪蛋白经蛋白酶降解后产生可溶于TCA、具有高紫外线吸收率的偶氮肽。这一偶氮酪蛋白测定法广泛用于评估细菌在葡萄糖和无机盐合成底物上细菌发酵产生的蛋白酶量。[2]

应用

偶氮酪蛋白已用作测定蛋白酶活性的底物。[3][4][5]
偶氮酪蛋白是一种炎症因子,可用于在实验动物中诱导淀粉样蛋白A淀粉样变性。
偶氮酪蛋白是一种非特异性蛋白酶底物。 酪蛋白的水解将偶氮染料释放至培养基中,其可通过培养基在440nm处的吸光度进行检测。

To overcome the metal restriction imposed by the host's nutritional immunity, pathogenic bacteria use high metal affinity molecules called metallophores. Metallophore-mediated metal uptake pathways necessitate complex cycles of synthesis, secretion, and recovery of the metallophore across the bacterial envelope. We
