背景资料: Enteropeptidase or enterokinase is an enzymeinvolved in human digestion. It is produced by cells in the duodenum wall, and is secreted from duodenum’s glands, the crypts of Lieberk?hn, whenever ingested food enters the duodenum from the stomach. Enteropeptidase has the critical job of turning trypsinogen(a zymogen) to trypsin, indirectly activating a number of pancreaticdigestive enzymes.Enteropeptidase is a serine proteas猪肠肽酶/肠激酶蛋白是在猪来源的组织细胞内提取纯化的,因此具有很高的活性和特异性以及纯度,并保证没有其他蛋白酶类.猪肠肽酶/肠激酶是一条单链、非糖基化的多肽链,包含有个氨基酸,分子量为kDa.该猪肠肽酶/肠激酶蛋白最终由标准的色谱技术纯化出.nzyme(EC3.4.21.9). Enteropeptidase is a part of the Chymotrypsin-clan of serine proteases, and is structurally similar to these proteins.
