      DescriptionLysargiNase
      Alternate Names
      • LysargiNase mirrors trypsin for protein C-terminal and methylation-site identification
      Background InformationLysargiNase is a metalloproteinase found in the thermophilic archaea Methanosarcina acetivorans. It specifically cleaves before lysine and arginine residues in proteins. This cleavage results in peptides with molecular weights similar to tryptic peptides, but with N-terminal lysine or arginine residues that can be fragmented with b ion-dominated spectra. This can improve protein C-terminal peptide identification and several arginine rich phosphosite assignments. Unlike with trypsin, LysargiNase cleavage also occurs at methylated lysine and arginine, allowing detection of these epigenetic modifications.

      Product Information
      Components
      • Each vial contains 20 µg LysargiNase, prepared by recombinant expression in E. coli and lyophilized from buffer.
      PresentationEach vial contains 20 µg LysargiNase, prepared by recombinant expression in E. coli and lyophilized from buffer. Upon reconstitution in 20 µL water, the enzyme is in 50 mM HEPES, 5 mM CaCl2, pH 7.5.
      Applications
      ApplicationLysargiNase is suitable for peptide or protein digestion in solution or in gel.
      Application NotesLysargiNase is suitable for peptide or protein digestion in solution or in gel. It is active under a variety of solvent conditions including 5 mM TCEP, 5% methanol, 5% acetonitrile, 0.8 M urea, 0.1% RapiGest, 1% deoxycholate, 0.2% SDS and 1% NP-40. It is active up to 55°C at pH 6 – 9. LysargiNase is reversibly inhibited by 1, 10-phenanthroline, EDTA and other calcium and zinc chelating agents. For peptide or protein digestion, a ratio of between 1:100 to 1:20 (w/w) enzyme:substrate is recommended.
