3HDI - PubMed Abstract: 
The M16 family of zinc peptidases comprises a pair of homologous domains that form two halves of a "clam-shell" surrounding the active site. The M16A and M16C subfamilies form one class ("peptidasomes"): they degrade 30-70 residue peptides, and adopt both open and closed conformations ...
