General description
LysargiNase 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.
LysargiNase is suitable for peptide or protein digestion in solution or in gel.
Application
LysargiNase is suitable for peptide or protein digestion in solution or in gel.
LysargiNase 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.

Methods for the selective labeling of biogenic functional groups on peptides are being developed and used in the workflow of both current and emerging proteomics technologies, such as single-molecule fluorosequencing. To achieve successful labeling with any one method requires that

The metzincin clan encompasses several families of zinc-dependent metalloproteases with proven function both in physiology and pathology. They act either as broad spectrum protein degraders or as sheddases, operating through limited proteolysis. Among the structurally uncharacterized metzincin families are the

Characterization of protein termini is essential for understanding how the proteome is generated through biological processes such as post-translational proteolytic events. Here, we introduce a practical protocol for terminomics to achieve simple and sensitive N- and C-terminal peptide enrichment. We

To improve proteome coverage and protein C-terminal identification, we characterized the Methanosarcina acetivorans thermophilic proteinase LysargiNase, which cleaves before lysine and arginine up to 55 °C. Unlike trypsin, LysargiNase-generated peptides had N-terminal lysine or arginine residues and fragmented with b
