Enterokinase human

Cat. No.: E755277

GRADE & PURITY Recombinant, for Cell culture, ≥90%(SDS-PAGE&HPLC), expressed in CHO cells,

Overview

Human Enterokinase is expressed as a linear 1019 amino acid polypeptide precursor glycoprotein. Proteolytic processing of this precursor generates the biologically active form of enterokinase, which consists of two polypeptide chains (heavy chain and light chain) held together by a single disulfide bond, resulting in formation of a biologically active heterodimer. The heavy chain consists of 784 amino acid residues, and the light consists of 235 amino acid residues. The mRNA is present in the proximal small intestine, and the protein is in enterocytes of the duodenum and proximal jejunum. The gene is mapped to human chromosome 21q21.

Biochemical and Physiological Mechanisms

Proteases (also called proteolytic enzymes, peptidases, or proteinases) are enzymes that hydrolyze the amide bonds within proteins or peptides. Most proteases act in a specific manner, hydrolyzing bonds at or adjacent to specific residues or a specific se

Frequently Asked Questions

What does for cell culture mean?

for cell culture indicates that the product has been processed and tested for cell culture and tissue engineering. Specifications may include endotoxin limits, microbial controls, sterility, low DNase/RNase/protease activity, and verified biological activity where relevant.

What does Recombinant mean?

Recombinant is a defined analytical purity tier suitable for workflows requiring a specific validated property. It specifies a minimum assay percentage, controlled limits on common impurities (water, heavy metals, residue on ignition), and lot-to-lot consistency. Recombinant is one of several purity tiers — choose based on the sensitivity and regulatory requirements of your method.
