Different hydrophobic glycoproteins are associated to native biliary vesicles, which are the major carrier of biliary cholesterol. Some of these proteins promote cholesterol crystallization, a key step in cholesterol gallstone formation.

A Radiochemical Assay for Aminopeptidase N
We developed an assay for aminopeptidase N (AmN) in which substrate, Arg-Phe-[3H]anilide (24.9 Ci/mmol), can be used at concentrations (1-200 nM) well below Km (12 microM) and at or below enzyme concentration ([E]). Such reaction conditions simulate those in vivo where peptide hormones in picomolar concentrations (> [E]. Arg-Phe-[3H]anilide can be used

Expression of Aminopeptidase N on Human Choriocarcinoma Cells and Cell Growth Suppression by the Inhibition of Aminopeptidase N Activity [PDF]
We previously found that an aminopeptidase inhibitor, ubenimex (bestatin), had a growth‐suppressive effect on Choriocarcinoma cell lines in vitro. To clarify the mechanism of this action, we investigated the expression of aminopeptidase N (AP‐N/CD13) on Choriocarcinoma cells and other human tumor cells. Two Choriocarcinoma cell lines, NaUCC‐4 and Be Wo,

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Aminopeptidase N (APN) is a transmembrane metallopeptidase, which participates in the tumor progress such as proliferation, attachment, angiogenesis and tumor invasion. All of this makes APN as a good chemical therapeutic anti-tumor target. In the present study, we got a novel compound 16l which markedly inhibited the enzyme activity of porcine APN ...

Urinary aminopeptidase activities as early and predictive biomarkers of renal dysfunction in cisplatin-treated rats. [PDF]
This study analyzes the fluorimetric determination of alanyl- (Ala), glutamyl- (Glu), leucyl-cystinyl- (Cys) and aspartyl-aminopeptidase (AspAp) urinary enzymatic activities as early and predictive biomarkers of renal dysfunction in cisplatin-treated ...

Further Characterization of Aminopeptidase-N as a Receptor for Coronaviruses [PDF]
We recently reported that porcine aminopeptidase-N (pAPN) acts as a receptor for transmissible gastroenteritis virus (TGEV). In the present work, we addressed the question of whether TGEV tropism is determined only by the virus-receptor interaction. To this end, different non-permissive cell lines were transfected with the porcine APN cDNA and tested ...

Impaired angiogenesis in aminopeptidase N-null mice [PDF]
Aminopeptidase N (APN, CD13; EC 3.4.11.2) is a transmembrane metalloprotease with several functions, depending on the cell type and tissue environment. In tumor vasculature, APN is overexpressed in the endothelium and promotes angiogenesis.

Contribution of porcine aminopeptidase N to porcine deltacoronavirus infection
Porcine deltacoronavirus (PDCoV), a member of genus Deltacoronavirus, is an emerging swine enteropathogenic coronavirus (CoV). Although outstanding efforts have led to the identification of Alphacoronavirus and Betacoronavirus receptors, the receptor for
