General description

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

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.

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.

The hinge region of human IgG2 contains four cysteine residues involved in disulfide linkages between the heavy chains, as well as the heavy and light chains. These linkages provide the fundamental framework of three distinct IgG2 disulfide isoforms recently described.
