Abstract:
Effects of adenosine on purified rat liver phosphofructokinase and phosphoglycerate kinase activity were investigated in vitro. Stimulation by adenosine of the phosphofructokinase has been observed at low concentrations, but the activity was markedly inhibited at high concentrations. Adenosine was an inhibitor of the phosphoglycerate kinase : Lineweaver-Burk analysis indicated that adenosine inhibition was competitive with ATP and non competitive with 3-phosphoglycerate. An interpretation of these results is proposed.
