Caffeine effect on adenosine deaminase catalysis: A new look at the effect of caffeine on adenosine deaminase activity
The effect of physiological concentrations of caffeine (purified from Persian tea) on adenosine deaminase (ADA) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mM Tris-HCl buffer (pH 7.3) at 37°C was investigated, using UV-VIS spectroscopy. ADA exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...
متن کاملHuman Adenosine Deaminase
Human erythrocyte adenosine deaminase has been purified approximately 800,000-fold to apparent homogeneity using antibody affinity chromatography. The enzyme was shown to be a single polypeptide chain with an estimated molecular weight of approximately 38,000. The three electrophoretic forms of erythrocyte adenosine deaminase purified simultaneoudy by this technique were indistinguishable by so...

متن کاملHuman adenosine deaminase expression in mice.
A replication defective retroviral vector containing a human adenosine deaminase (hADA) cDNA was produced by GP + E-86 packaging cells at high titer. We report long-term expression of hADA in the hematopoietic tissues of mice transplanted with bone marrow cells infected by in vitro co-cultivation with vector producing cells. Western analysis using an hADA-specific antibody allowed detection of ...
متن کاملAdenosine-mediated mast cell degranulation in adenosine deaminase-deficient mice.
Adenosine is a signaling nucleoside that has been suggested to play a role in asthma in part through its ability to influence mediator release from mast cells. Adenosine levels are elevated in the lungs of asthmatics, further implicating this molecule in the regulation of lung inflammation and suggesting that animal models exhibiting endogenous increases in adenosine will be useful for the anal...
