This domain consists of 4 beta strands and two alpha helices which make up the dimerisation surface of members of the M20 family of peptidases [1]. This family includes a range of zinc metallopeptidases belonging to several families in the peptidase classification [2]. Family M20 are Glutamate carboxypeptidases. Peptidase family M25 contains X-His dipeptidases.	Domain
