Xaa-Arg dipeptidase (EC 3.4.13.4, aminoacyl-lysine dipeptidase, N2-(4-amino-butyryl)-L-lysine hydrolase, X-Arg dipeptidase) is an enzyme.[1] This enzyme catalyses the following chemical reaction
Preferential hydrolysis of Xaa!Arg, Xaa!Lys or Xaa!ornithine dipeptides
This enzyme is widely distributed in mammals.
