Kallikrein-2 Protein, Human (HEK293, His)

The Kallikrein-2 protein is a member of the glandular kallikrein family and is critical in the enzymatic process as it selectively cleaves the Met-Lys and Arg-Ser bonds in kininogen, thereby releasing Lys-bradykinin . This proteolytic activity contributes to the production of bradykinin, a bioactive peptide with multiple roles in regulating blood pressure, inflammation, and vascular permeability. Kallikrein-2 Protein, Human (HEK293, His) is the recombinant human-derived Kallikrein-2 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of Kallikrein-2 Protein, Human (HEK293, His) is 243 a.a., with molecular weight of ~32.0 kDa.

Kallikrein-2 is a member of the glandular kallikrein family, exhibiting enzymatic activity by cleaving Met-Lys and Arg-Ser bonds in kininogen, resulting in the release of Lys-bradykinin. As part of the kinin-kallikrein system, Kallikrein-2 contributes to the generation of bradykinin, a potent vasoactive peptide involved in the regulation of blood pressure, inflammation, and vascular permeability. By specifically cleaving these bonds in kininogen, Kallikrein-2 plays a crucial role in the controlled release of Lys-bradykinin, influencing downstream physiological processes.

Measured by its ability to cleave a flourogenic peptide substrate Z-Phe-Arg-7-amido-4-methylcoumarin (FR-AMC). The specific activity is 198 pmol/min/μg.
