Dipeptidyl-aminopeptidases and aminopeptidases in Dictyostelium discoideum

Biochemical and Biophysical Research Communications, 1985
Extracts prepared from culminating cells of Dictyostelium discoideum have been found to contain dipeptidyl-aminopeptidases I (EC 3.4.14.1), II (EC 3.4.14.2), III (EC 3.4.14.4), arginine aminopeptidase (EC 3.4.11.6) and valine aminopeptidase. Dipeptidyl-aminopeptidase III was the most active of the dipeptidyl-aminopeptidases; its molecular weight was ...

Study on aminopeptidase A

Histochemistry, 1980
A comparative biochemical and histochemical investigation of aminopeptidase A (APA, E.C. 3.4.11.7) was carried out. α-Glu-1NA, α-Glu-2NA, α-Glu-MNA and Asp-2NA were used as substrates, Fast Blue B (FBB), hexazotized new fuchsin (HNF) and hexazonium-p-rosaniline (HPR) as coupling agents.

Comparison of leucine aminopeptidase and aminopeptidase III activities in lens

Current Eye Research, 1996
To evaluate the relative contribution of leucine aminopeptidase and aminopeptidase III activities to the total aminopeptidase activity in bovine and human lenses under in vivo pH conditions.Bovine and human lens extracts were fractionated on a Sephadex G-200 column at pH 6.9 and 8.5 and all the fractions were assayed with Leu-pNA and Arg-pNA as ...

Aminopeptidases and Angiogenesis

Endothelium, 2003
A number of proteases, including matrix metalloproteinases and plasminogen activators, have been shown to be involved in angiogenesis. In addition, recent reports suggest that aminopeptidases also play roles in angiogenesis. These peptidases regulate the N-terminal modification of proteins and peptides required in processes such as maturation ...

The yeast aminopeptidase Y

Canadian Journal of Microbiology, 1988
A metal-dependent aminopeptidase (EC 3.4.11.-), designated APase Y, has been purified to homogeneity by conventional methods. The enzyme is composed of a single polypeptide chain with molecular mass of 102 kilodaltons, estimated by sodium dodecyl sulphate – polyacrylamide gel electrophoresis, with a blocked N-terminal amino acid.

Aminopeptidase activity of Capnocytophaga

Journal of Periodontal Research, 1982
Studies have shown that Capnocytophaga species are unique among the periodonlal microorganisms so far tested in that they produce marked leucine aminopeptidase, valine aminopeptidase, and cystine aminopeptidase activities. In this paper, we used the expanded API ZYMAP (API‐System, La Balme les Grottes, France) system to survey 18 Capnocytophaga strains

Aminopeptidase A in human placenta

Biochimica et Biophysica Acta (BBA) - Enzymology, 1981
Abstract Aminopeptidase A ( l -α-aspartyl( l -α-glutamyl)-peptide hydrolase, EC 3.4.11.7) was found in human placenta, partially purified from it and briefly characterized in comparison with the placental leucine aminopeptidase. The aminopeptidase A could be separated from leucine aminopeptidase after trypsin digestion followed by Sephacryl S-300 ...

Aminopeptidase in Elastotic Skin

Archives of Dermatology, 1962
Although peptidases have been found to be localized principally in the cellular, as opposed to the fibrous, elements of the skin, 1,2 the presence of an aminopeptidase in the fibrous dermal structure in elastotic skin has not been reported. An aminopeptidase can indeed be demonstrated in the elastotic skin by histochemical staining methods which ...

Inhibition of aminopeptidases by aminophosphonates

Biochemistry, 1989
More than 30 aminophosphonates were synthesized to probe how the structural changes introduced into the phosphonic acid analogue of leucine, a potent inhibitor of cytosolic leucine aminopeptidase (Giannousis & Bartlett, 1987), affect their ability to inhibit cytosolic (EC 3.4.11.1) and microsomal (EC 3.4.11.2) aminopeptidases.
