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.
Other Notes
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.

Formation of covalently bound protein adducts with 2-arylpropionic acids (2-APAs) has been proposed as a possible explanation for hypersensitivity and toxic responses to chiral carboxylic acid drugs. To identify the cellular proteins chemically modified with optically active (S)-ibuprofen, we generate

Recombinant monoclonal antibodies (mAbs) are an emerging therapeutic area. However, there are few reports on disulfide bond assignment of recombinant mAbs. This work describes the complete disulfide bond assignment of a recombinant immunoglobulin G4 (IgG4) mAb. N-ethylmaleimide (NEM) was used
