胰蛋白酶已被用于一项评估戊型肝炎病毒和人类星状病毒之间的相似性的研究。在一项研究中也使用了胰蛋白酶来表征培养原代成人上皮祖细胞或干细胞的一种独特技术。应用： 胰蛋白酶分子有两个结构域：一个与酶的活性位点和色氨酸残基有关；另一种与 8-苯胺萘-1-磺酸结合有关。 胰蛋白酶是一种丝氨酸蛋白酶。胰腺可产生前体胰蛋白酶原并将其分泌到肠中。肠粘膜中的肠激酶可将胰蛋白酶原转化为胰蛋白酶。 The trypsin molecule has two domains: one is related to the enzyme active site and the tryptophan residues; the other is related to the 8-anilinonaphthalene-1-sulfonate binding. Trypsin is a serine protease. The pancreas produce the precursor trypsinogen and secretes it to the intestine. Trypsinogen is converted to trypsin by enterokinase in the intestinal mucous membrane. Application: Trypsin has been used in a study to assess the similarities between the hepatitis E virus and human astrovirus. Trypsin has also been used in a study to characterize a unique technique for culturing primary adult human epithelial progenitor, or stem, cells.
