Localization of adenosine deaminase and adenosine deaminase complexing protein in rabbit heart. Implications for adenosine metabolism.
The distribution of adenosine deaminase and adenosine deaminase complexing protein in rabbit heart has been compared using immunohistochemical staining procedures. Sections (4-5 microns) of tissue fixed in Clarke's solution or paraformaldehyde and embedded in paraffin were stained by the peroxidase anti-peroxidase method for adenosine deaminase or complexing protein, using affinity purified ant...
متن کاملCharacterization of the adenosine deaminase-adenosine deaminase complexing protein binding reaction.
Glutaraldehyde-fixed membranes from rabbit kidney cortex were used to characterize binding of monomeric adenosine deaminase to the adenosine deaminase complexing protein. With the use of bovine adenosine deaminase it was shown that enzyme binding is a saturable, high affinity process. The K value for binding of the bovine enzyme was 11 nM. Maximum enzyme binding and rate of binding to a constan...
متن کاملClustered charged amino acids of human adenosine deaminase comprise a functional epitope for binding the adenosine deaminase complexing protein CD26/dipeptidyl peptidase IV.
Human adenosine deaminase (ADA) occurs as a 41-kDa soluble monomer in all cells. On epithelia and lymphoid cells of humans, but not mice, ADA also occurs bound to the membrane glycoprotein CD26/dipeptidyl peptidase IV. This "ecto-ADA" has been postulated to regulate extracellular Ado levels, and also the function of CD26 as a co-stimulator of activated T cells. The CD26-binding site of human AD...
متن کاملHuman Adenosine Deaminase Binding Protein
In many human tissues adenosine deaminase exists as a complex composed of two proteins; one protein has adenosine deaminase activity while the other represents a binding protein with no other known binding activity. A rapid, quantitative assay for human adenosine deaminase binding protein has been developed utilizing ‘251-labeled calf adenosine deaminase. In addition this binding protein has be...
متن کاملSerum Adenosine Deaminase Activity and C-Reactive Protein Levels in Patients with Brucellosis
Background and Objective: Brucellosis is a main transmittable zoonotic disease, which is endemic, and a common health burden in Iran. Adenosine deaminase (ADA) is an essential enzyme which is involved in purine metabolism and its role in immune system is very important. The aim of this study was to determine serum changes of ADA and C-reactive protein (CRP) levels in patients with brucellosi...
