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.
