| X-His dipeptidase |
[EC 3.4.13.3] an enzyme of the hydrolase class that catalyzes the cleavage of the dipeptide carnosine into component amino acids β-alanine and histidine; it also acts on some other aminoacyl-L-histidine dipeptides. The tissue isozyme requires zinc ions and does not hydrolyze anserine or homocarnosine; the serum isozyme requires cadmium and does hydrolyze anserine and homocarnosine. Deficiency of the serum isozyme causes serum carnosinase deficiency. Called also carnosinase and aminoacyl-histidine dipeptidase. See also homocarnosinase.
