IUBMB Enzyme Nomenclature

EC 3.4.21.50

Accepted name: lysyl endopeptidase

Reaction: Preferential cleavage: Lys, including -LysPro-

Other names: Achromobacter proteinase I (also see Comment); Achromobacter lyticus alkaline proteinase I; protease I; achromopeptidase; lysyl bond specific proteinase

Comments: From Achromobacter lyticus [6]. Enzymes with similar specificity are produced by Lysobacter enzymogenes (Endoproteinase Lys-C; [3]) and Pseudomonas aeruginosa (Ps-1; [4]). In peptidase family S1 (trypsin family)
