Selective precipitation of phosphofructokinase, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase from rat erythrocyte hemolysates by polyethylene glycol. 1986

M C Tejedor, and C Delgado, and A Rubio, and J Luque

Precipitation profiles of phosphofructokinase, glucose-6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase have been established in the range of 0-16% PEG at different pH values. Precipitation generally occurred between narrow limits of polyethylene glycol. The polymer concentration needed to reach any level of enzyme precipitation is dependent on pH. Particular conditions (% PEG and pH) for the selective enzyme enrichment have been determined.

D008297 Male Males
D010732 Phosphofructokinase-1 An allosteric enzyme that regulates glycolysis by catalyzing the transfer of a phosphate group from ATP to fructose-6-phosphate to yield fructose-1,6-bisphosphate. D-tagatose- 6-phosphate and sedoheptulose-7-phosphate also are acceptors. UTP, CTP, and ITP also are donors. In human phosphofructokinase-1, three types of subunits have been identified. They are PHOSPHOFRUCTOKINASE-1, MUSCLE TYPE; PHOSPHOFRUCTOKINASE-1, LIVER TYPE; and PHOSPHOFRUCTOKINASE-1, TYPE C; found in platelets, brain, and other tissues. 6-Phosphofructokinase,6-Phosphofructo-1-kinase,Fructose-6-P 1-Kinase,Fructose-6-phosphate 1-Phosphotransferase,6 Phosphofructokinase,Phosphofructokinase 1
D010734 Phosphogluconate Dehydrogenase An enzyme of the oxidoreductase class that catalyzes the reaction 6-phospho-D-gluconate and NADP+ to yield D-ribulose 5-phosphate, carbon dioxide, and NADPH. The reaction is a step in the pentose phosphate pathway of glucose metabolism.
