Product introduction

Lysyl endonuclease, also known as lysyl endopeptidase, Lys-C endonuclease, is a serine protease originally discovered and isolated from soil bacteria by Masaki et al. The enzyme is highly specific and specifically cleaves peptide bonds at the carboxy terminus of lysine residues and S-aminoethyl cysteine residues. It has also been reported to have a small amount of non-specific cleavage. 

This enzyme is a very valuable tool enzyme for protein sequence analysis and bioproduct production. The enzyme can be used alone or in combination with other proteases, and the digested protein can be used for peptide mapping and preparation of the protein of interest. The product is a recombinant lysyl endonuclease powder which is isolated and purified from recombinant E. coli and then freeze-dried.This product is a biochemical-grade genetically engineered enzyme. It does not contain enzyme inhibitors such as DFP, PMSF and TLCK. It has the same activity and specificity as natural lysyl endo enzyme and can be used in biological products such as insulin and GLP-1.
