  • Title: Fructose-2,6-bisphosphate in rat mesenteric lymph nodes.
    Author: Abuelgassim AO, Khoja SM.
    Journal: Int J Biochem; 1988; 20(10):1185-8. PubMed ID: 2977764.
    Abstract:
    1. The fructose-2,6-bisphosphate (Fru-2,6-P2) content of mesenteric lymph nodes was measured in rats. 2. The effects of Fru-2,6-P2 on the activity of 6-phosphofructo-1-kinase (PFK-1) from rat mesenteric lymph nodes were also studied. 3. The affinity of the enzyme for fructose-6-phosphate was increased by Fru-2,6-P2 whereas the inhibition of the enzyme with high concentrations of ATP was released by Fru-2,6-P2. 4. The activity of lymphocyte PFK-1 was highly stimulated in a simultaneous presence of low concentrations of AMP and Fru-2,6-P2. 5. These results show that rat lymphocyte PFK-1 is highly regulated with Fru-2,6-P2 which means that glycolysis in rat lymphocytes is controlled by Fru-2,6-P2.
