Catalysis of the hydrolysis of a dipeptide. [https://www.ebi.ac.uk/merops/about/glossary.shtml#DIPEPTIDASE, PMID:19879002]
Dipeptidase activity refers to the enzymatic hydrolysis of dipeptides, which are molecules composed of two amino acids linked by a peptide bond. These enzymes play a crucial role in protein digestion and metabolism, breaking down dipeptides into their constituent amino acids. This process is essential for the absorption and utilization of amino acids by the body. Dipeptidases are highly specific for the type of amino acids present in the dipeptide substrate, and their activity can be influenced by factors such as pH, temperature, and the presence of inhibitors. Dipeptidases are found in various organisms, including bacteria, fungi, plants, and animals, and they are involved in a range of physiological processes. For example, in humans, dipeptidases are present in the small intestine, where they contribute to the final stages of protein digestion. They are also found in other tissues, such as the kidneys and liver, where they play roles in amino acid metabolism and detoxification.'
