Lysyl endopeptidase (, ''Achromobacter proteinase I'', ''Achromobacter lyticus alkaline proteinase I'', ''protease I'', ''achromopeptidase'', ''lysyl bond specific proteinase'', and ''caseinase'') is an

enzyme An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different mol ...

chemical reaction A chemical reaction is a process that leads to the chemistry, chemical transformation of one set of chemical substances to another. When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an Gibbs free energy, ...

: Preferential cleavage: Lys-, including -Lys-Pro- This enzyme is isolated from '' Lysobacter enzymogenes''. It is produced by the human body and by '' Achromobacter lyticus'' that can help break down the protein

casein Casein ( , from Latin ''caseus'' "cheese") is a family of related phosphoproteins (CSN1S1, αS1, aS2, CSN2, β, K-casein, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of ...

milk Milk is a white liquid food produced by the mammary glands of lactating mammals. It is the primary source of nutrition for young mammals (including breastfeeding, breastfed human infants) before they are able to digestion, digest solid food. ...
