Lysyl endopeptidase (
EC3.4.21.50, Achromobacter proteinase I, Achromobacter lyticus alkaline proteinase I, protease I, achromopeptidase, lysyl bond specific proteinase, and caseinase) is an
enzyme.[1][2][3][4][5][6] This enzyme
catalyses the following
chemical reaction
It is produced by the human body and by Achromobacter lyticus[7] that can help break down the protein
casein in
milk into smaller peptides and amino acids.[8]
