General description

Endoproteinase Lys-C is an enzyme that preferentially cleaves at the carboxyl side of lysine residues.

Unit Definition

One unit will hydrolyze 1.0 μmole of N-p-tosyl-Gly-Pro-Lys p-nitroanilide per min at pH 7.7 at 25 °C.

Application

Endoproteinase Lys-C from Lysobacter enzymogenes is useful in the determination of primary structures of proteins. It has been used in a study to investigate the evidence for trisulfide bonds in a recombinant variant of a human IgG2 monoclonal antibody.

Endoproteinase Lys-C has been used for the digestion monoclonal antibodies for disulfide bond assignment.

Biochem/physiol Actions

Endoproteinase Lys-C inactivates the enzyme inositol monophosphatase by cleaving it at a single site directly after Lys 36.
