Cytosol AP (Cyt-AP), deblocking AP (DAP) and AP N (APN) remove N-terminal amino acids. The AP are classified by the amino acid which they hydrolyze. Other types of AP are: Cold-activated AP (Col-AP) Heat stable AP from Thermus thermophilus (AmpT) AP from Staphylococcus aureus (AmpS) SGAP from Stereomyces griseus. See details in Streptomyces griseus Aminopeptidase (SGAP). Alanine aminopeptidase is called aminopeptidase N. See details in Aminopeptidase N. Aminopeptidases catalyze a release of an N-terminal amino acid from a peptide, amide, or arylamide. Beta-peptidyl AP (BapA) cleaves N-terminal β-homoamino acid from peptides of length 2 to 6.[1] Aminopeptidase from Aeromonas proteolytica[2] The selective inhibition of an , a hydrolase, by derivatives is reported. Based on our findings about 8-HQ-based Zn2+ fluorophores, it was hypothesized that 8-HQ derivatives have the potential to function as specific inhibitors of Zn2+ enzymes, especially dinuclear Zn2+ hydrolases. Inhibitory assays of 8-HQ derivatives against AAP disclosed that the 8-HQ and 5-substituted 8-HQ′s are competitive inhibitors for AAP with inhibition constants (Ki) of 0.16—29 μM at pH 8.0. (1.3 Å resolution) as well as fluorescence titrations of these drugs with AAP confirmed that , in which the in the active site of AAP and the (PDB code: 3vh9). of free AAP (colored green) containing Zn2+-bound water molecule (H2O or OH-; red sphere) (1rtq) bridging two Zn2+ and AAP–8-HQ complex (darkmagenta, 3vh9). Two Zn2+ are depicted as magenta spheres. S. griseus aminopeptidase S. griseus aminopeptidase (SGAP) cleaves the N-terminal amino acid from a peptide or protein, and is specific for larger hydrophobic acids, especially leucine. No cleavage occurs if the next residue is proline. The of the enzyme contains two Zn2+ ions with His85 and Asp160 as ligands for one ion, and Glu132 and His247 as ligands for the second ion. Asp97 is a common ligand to both ions. What appears to be a phosphate anion is bound to both zinc atoms, replacing the water molecule/hydroxide ion normally found in this class of enzyme. See details of SGAP in Streptomyces griseus Aminopeptidase (SGAP).
