Trypsinogen 是一种在胰腺中合成的酶原，到达小肠腔后，肠激酶激活胰蛋白酶，在 Lys6 - Ile7 连接处打开六肽键，从而产生活性酶。该单条多肽链由 229 个氨基酸组成，并由六个二硫键稳定，进一步自催化将额外的胰蛋白酶原转化为胰蛋白酶，胰蛋白酶最初以 β-胰蛋白酶的形式存在，然后在 Lys131 - Ser132 位点发生自溶，形成 α-胰蛋白酶。作为丝氨酸蛋白酶，胰蛋白酶的活性位点为 His46 和 Ser183，在 pH 值范围为 7 至 9 时表现出最佳酶活性。

生物活性

Trypsinogen, a proenzyme synthesized in the pancreas, is activated to form trypsin by enterokinase upon reaching the small intestine lumen, where it opens a hexapeptide bond at the Lys6 - Ile7 junction, leading to the production of the active enzyme. This single polypeptide chain, composed of 229 amino acids and stabilized by six disulfide bridges, further autocatalytically converts additional trypsinogen into trypsin, which is initially present as β-trypsin before undergoing autolysis at the Lys131 - Ser132 site to form α-trypsin. As a serine protease, trypsin features His46 and Ser183 at its active site and exhibits optimal enzymatic activity at a pH range of 7 to 9.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
