Overview
New York, NY – June 27, 2025 – Global Recombinant Lysyl Endopeptidase Market size is expected to be worth around US$ 0.8 Billion by 2034 from US$ 0.5 Billion in 2024, growing at a CAGR of 5.4% during the forecast period 2025 to 2034. In 2024, North America led the market, achieving over 38.5% share with a revenue of US$ 0.2 Billion.
Recombinant Lysyl Endopeptidase (Lys-C), a genetically engineered proteolytic enzyme, is gaining prominence across biopharmaceutical and proteomics industries due to its precision in cleaving peptide bonds at the carboxyl side of lysine residues. Derived through recombinant expression, this enzyme provides high specificity and stability, enabling consistent and efficient protein digestion under denaturing conditions, including in the presence of urea or guanidine hydrochloride.
Lys-C is particularly valuable in mass spectrometry workflows, allowing researchers to generate peptides with predictable cleavage patterns, leading to improved sequence coverage and protein identification. Its application is crucial for bottom-up proteomics, peptide mapping, and quality control in biotherapeutic production.
Compared to traditional trypsin digestion, Recombinant Lys-C demonstrates enhanced performance when working with proteins resistant to cleavage or prone to miscleavage. The enzyme is expressed in E. coli and undergoes rigorous purification to ensure it is free from contaminating proteases and endotoxins, making it suitable for GMP-compliant workflows.
Leading suppliers are optimizing this enzyme for high-purity formats, offering lyophilized and solution-based products that integrate easily into automated proteomic pipelines. Its stability, activity retention, and low autolysis rate continue to expand its adoption in pharmaceutical research, diagnostics, and academic laboratories.
