Comments [?]

Function Probable zinc metalloprotease whose natural substrate is unknown.
Cofactor Zn(2+)
Note: Binds 2 Zn(2+) ions per subunit. One is catalytic, whereas the other seems to have a structural role.
Subunit Monomer.
Similarity Belongs to the peptidase M54 family.

Comments Although it has not been proved in prokaryotes, its function as metalloprotease is probable due to the strong similarities with the AMZ1 and AMZ2 enzymes. See: RX PubMed=15972818; DOI=10.1074/jbc.M504533200; RA Diaz-Perales A., Quesada V., Peinado J.R., Ugalde A.P., Alvarez J., RA Suarez M.F., Gomis-Rueth X., Lopez-Otin C.; RT "Identification and characterization of human archaemetzincin-1 and - RT 2, two novel members of a family of metalloproteases widely RT distributed in archae."; RL J. BiolQ400G9. Chem. 280:30367-30375(2005). The family has been identified in Archaea and described in: RX PubMed=12746556; RA Gomis-Rueth F.X.; RT "Structural aspects of the metzincin clan of metalloendopeptidases."; RL Mol. Biotechnol. 24:157-202(2003).
