'''Crystal Structure of the Aminopeptidase of Aeromonas proteolytica at pH 4.7'''
===Crystal Structure of the Aminopeptidase of Aeromonas proteolytica at pH 4.7===




==Overview==
<!--  
The aminopeptidase from Aeromonas proteolytica (AAP) contains two zinc ions in the active site and catalyzes the degradation of peptides. Herein we report the crystal structures of AAP at 0.95-A resolution at neutral pH and at 1.24-A resolution at low pH. The combination of these structures allowed the precise modeling of atomic positions, the identification of the metal bridging oxygen species, and insight into the physical properties of the metal ions. On the basis of these structures, a new putative catalytic mechanism is proposed for AAP that is likely relevant to all binuclear metalloproteases.
The line below this paragraph, {{ABSTRACT_PUBMED_16596389}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 16596389 is the PubMed ID number.
