Web95%) by affinity chromatography. The peptide substrate GST-Melittin with enterokinase recognition site was completely cleaved by the purified MBP-hEK L at the molar ratio of 1:5000 (enzyme:substrate). Tricine SDS-PAGE analysis showed that the activity of MBP-hEK L was approximately seven times that of bovine enterokinase catalytic WebEnterokinase, also called enteropeptidase, is a serine protease involved in digestion. It catalyzes the conversion of trypsonigen into its active form of typsin, which begins the activation of pancreatic digestive enzymes. In humans, it is produced in the duodenum. A disulfide-linked heterodimer in most species, it consists of a heavy chain of ...

Webulation factor X (factor Xa),1 enterokinase (hereafter referred to by its more appropriate moniker enteropeptidase), and a-thrombin were the reagents of choice for removing affinity tags, yet the liter-ature is repletewith reportsof fusionproteins thatwere cleavedby these proteases at locations other than the designed site. Over the WebDescription. The Enterokinase Cleavage Capture Kit is designed for highly specific cleavage of fusion proteins followed by rapid, affinity-based capture and removal of enterokinase. Following cleavage of the target protein, rEK is removed with > 99% efficiency from the reaction by affinity capture on EKapture™ Agarose. WebEnterokinase specifically cleaves proteins at the specific sequence, Asp-Asp-Asp-Asp-Lys-X, with X being any amino acid other than proline, at the C-terminal end of the … tuluza prancuzija
