Beta-Ala-His dipeptidase (EC 3.4.13.20, serum carnosinase) is an enzyme. This enzyme catalyses the following chemical reaction
- Preferential hydrolysis of the beta-Ala!His dipeptide (carnosine), and also anserine, Xaa!His dipeptides and other dipeptides including homocarnosine
This enzyme is present in the serum of humans and higher primates.
