KEX2 Protease

(Expressed in Pichia pastoris)

100% Animal Origin Free

CAS No: 99676-46-7 

Product Overview

Recombinant Kex2 Protease is a calcium-dependent serine protease engineered to mimic the high fidelity of the yeast Kexin-family endoprotease. 

Designed to specifically recognize and cleave the carboxyl peptide bond of dibasic amino acids—primarily Lys-Arg (K-R) and Arg-Arg (R-R)—our Kex2 Protease is the essential tool for manufacturers seeking to produce bioactive proteins from complex fusion precursors. 

Why Recombinant Kex2 Protease is the Industry Choice?

  • Superior Substrate Specificity: Recombinant Kex2 Protease does not cleave at isolated basic residues, ensuring that your target protein remains intact while only the fusion tag or pro-peptide is removed. 
  •  Animal-Free (AOF) Manufacturing: Our Kex2 is produced in a recombinant microbial system, making it completely free of animal-derived components, and ideal for clinical-grade therapeutic production. 
  • High Specific Activity: Optimized for rapid processing, allowing for low enzyme-to-substrate ratios that reduce costs and simplify downstream purification. 
  • Robust Performance: Retains high activity across a broad range of buffer conditions, specifically optimized for pH 7.0–9.0 in the presence of calcium ions. 

Applications

  • Site-Specific Tag Removal and pro-peptides from recombinant proteins to recover native protein structures. 
  • Specialized in the processing of secreted proteins, enzymes, and bioactive peptides in recombinant expression systems. 
  • A critical component for both research and large-scale industrial bioprocessing and downstream purification workflows. 
  • Reliable processive enzymatic cleavage for the synthesis and maturation of peptide-based therapeutics (e.g., Insulin, GLP-1). 
  • Ideal for the enzymatic digestion of proteins for high-resolution peptide mapping and amino acid sequencing studies. 
  • Used in the maturation of viral antigens expressed in recombinant systems to ensure correct folding and immunogenicity
