Abstract:
Blood–brain barrier (BBB) aminopeptidase activity was investigated using an in vitro model consisting of primary cultures of brain microvessel endothelium. Using two different substrates, both membrane-bound and soluble aminopeptidases were found to be associated with brain endothelium. That the enzyme activity was aminopeptidase activity was confirmed with the competitive inhibition of substrate degradation by typical aminopeptidase inhibitors puromycin and bestatin. The aminopeptidase activity was also competitively inhibited by enkephalin, met-enkephalin, and leu-enkephalin. Results from pa

Abstract:
ABSTRACT The effects of myoglobin on exopeptidases of Lactobacillus sake were determined. Inhibition of the aminopeptidases increased as the myoglobin concentration increased; aminopeptidase 3 was the most affected (90% inhibition). Aminopeptidases 1, 2, and 4 showed similar inhibition levels (around 60%). Myoglobin did not affect tripeptidase activity. Thus, myoglobin could limit amino acid generation in meat systems.

Abstract:
ABSTRACT During its intraerythrocytic phase, the most lethal human malarial parasite, Plasmodium falciparum, digests host cell hemoglobin as a source of some of the amino acids required for its own protein synthesis. A number of parasite endopeptidases (including plasmepsins and falcipains) process the globin into small peptides. These peptides appear to be further digested to free amino acids by aminopeptidases, enzymes that catalyze the sequential cleavage of N-terminal amino acids from peptides. Aminopeptidases are classified into different evolutionary families according to their sequence

Abstract:
During the erythrocytic stage of its life cycle, the human malaria parasite Plasmodium falciparum catabolizes large quantities of host-cell hemoglobin in an acidic organelle, the food vacuole. A current model for the catabolism of globin-derived oligopeptides invokes peptide transport out of the food vacuole followed by hydrolysis to amino acids by cytosolic aminopeptidases. To test this model, we have examined the roles of four parasite aminopeptidases during the erythrocytic cycle. Localization of tagged aminopeptidases, coupled with biochemical analysis of enriched food vacuoles, revealed t

Abstract:
A novel two-step enzyme-linked assay for aminopeptidase W is described and validated by comparison with other assays. L-alpha-Glutamyl-L-tryptophan (Glu-Trp) is a favoured substrate for this enzyme. With the use of glutamate dehydrogenase (EC 1.4.1.2) in a second step, the assay measured the release of free glutamate from L-alpha-glutamyl-L-tryptophan by the increase in NADH fluorescence. In the presence of 5 mM-1,10-phenanthroline and 50 microM-cilastatin the contribution of other membrane peptidases, in particular aminopeptidases N and A and microsomal dipeptidase in kidney, was very small.

Abstract:
Aminopeptidase N (APN), also known as CD13 antigen or membrane alanyl aminopeptidase, belongs to the M1 family of the MA clan of zinc metallopeptidases. In cancer cells, the inhibition of aminopeptidases including APN causes the phenomenon termed the amino acid deprivation response (AADR), a stress response characterized by the upregulation of amino acid transporters and synthetic enzymes and activation of stress-related pathways such as nuclear factor kB (NFkB) and other pro-apoptotic regulators, which leads to cancer cell death by apoptosis. Recently, APN inhibition has been shown to augment

Insulin-regulated aminopeptidase (IRAP) co-localizes with the glucose transporter 4 (GLUT4) in GLUT4 storage vesicles (GSV) in insulin-responsive cells. In response to insulin, IRAP is the only transmembrane enzyme known to translocate together with GLUT4 to the plasma membrane in adipocytes and muscle cells. Although the intracellular region of IRAP is associated with GLUT4 vesicle trafficking, the role of the aminopeptidase activity in insulin-responsive cells has not been elucidated. The aim of this study was to investigate whether the inhibition of the aminopeptidase activity of IRAP facil

Abstract:
ERAP1 is an aminopeptidase that is a component of antigen processing. To distinguish the role of ERAP1 from homologs ERAP2 and IRAP, I identified three specific ERAP1 inhibitors via a high-throughput screen. These compounds inhibit hydrolysis of a decamer peptide, and some inhibit ERAP1 in a cellular assay. These inhibitors enable dissection of ERAP1 mechanism. ERAP1 has been crystallized in two conformations: open and closed. I collected SAXS data on ERAP1 in the presence of various inhibitors. ERAP1 adopts an open conformation in solution, but some inhibitors stabilize the closed form. Compo
