Very diverse family. Attempts to define separate sub-families failed. Typically, either the N-terminal or C-terminal end is very divergent. But splitting into two domains would make very short families. All members except Swiss:Q03196 and Swiss:Q10993 are found. Pfam:PF00666 are related to this family but have not been included.	Domain

The MAM domain along with the associated Ig domain in type IIB receptor protein tyrosine phosphatases forms a structural unit (termed MIg) with a seamless interdomain interface. It plays a major role in homodimerisation of the phosphatase ectoprotein and in cell adhesion [2,3]. MAM is a beta-sandwich consisting of two five-stranded antiparallel beta-sheets rotated away from each other by approx 25 degrees, and plays a similar role in meprin metalloproteinases [4].	Domain

The members of this family are enzymes that cleave peptides. These proteases require zinc for catalysis. Members of this family contain two conserved disulphide bridges, these are joined 1-4 and 2-3. Members of this family have an amino terminal propeptide which is cleaved to give the active protease domain. All other linked domains are found to the carboxyl terminus of this domain. This family includes: Astacin Swiss:P07584, a digestive enzyme from Crayfish. Meprin, Swiss:Q16819, a multiple domain membrane component that is constructed from a homologous alpha and beta chain. Proteins involved in morphogenesis such as Swiss:P13497, and Tolloid from drosophila Swiss:P25723.	Domain
