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 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.

Inhibition of Aminopeptidase I

1978
The inhibition of aminopeptidase I from Eschericia coli K12 by several dipeptides, which are not hydrolyzed by the enzyme, has been examined quantitatively. The dissociation constants (K,) of three of these inhibitors with the enzyme have been determined.

Aminopeptidases: structure and function

The FASEB Journal, 1993
Aminopeptidases catalyze the cleavage of amino acids from the amino terminus of protein or peptide substrates. They are widely distributed throughout the animal and plant kingdoms and are found in many subcellular organelles, in cytoplasm, and as membrane components.
