Description
OverviewNative endoproteinase Lys-C from Lysobacter enzymogenes. Serine protease that specifically hydrolyzes amide and peptide ester bonds at the carboxylic side of lysine in peptides and proteins. Designed for protein sequencing or sequence verification, analysis of protein structural domains, and cleavage of fusion proteins. Inhibited by aprotinin, DFP, leupeptin, and TLCK. Suggested working concentration: 1:20 to 1:100 (protease:protein by weight) for sequence analysis.

DescriptionNative endoproteinase Lys-C from Lysobacter enzymogenes. Serine protease that specifically hydrolyzes amide and peptide ester bonds at the carboxylic side of lysine in peptides and proteins. Designed for protein sequencing or sequence verification, analysis of protein structural domains, and cleavage of fusion proteins. Inhibited by aprotinin, DFP, leupeptin, and TLCK.
FormLyophilized
FormulationLyophilized from 50 mM HEPES, 10 mM EDTA, 5 mg/ml raffinose, pH 8.0.
Recommended reaction conditions
Protocol 1. Dissolve the proteins to be sequenced in 25 mM Tris-HCl, pH 8.5, and 1 mM EDTA. For proteins that are difficult to solubilize, add urea, SDS, or guanidine-HCl to the digestion buffer prior to solubilization. If urea is used, add 20 mmol/l of methylamine. 2. The suggested working concentration is 1:20-1:100 (protease:protein by weight). 3. Incubate for 2-18 h at 37°C.
