Binding of MgATP to yeast phosphofructokinase. 1977

K Nissler, and W Schellenberger, and E Hofmann

Binding of MgATP to yeast phosphofructokinase was investigated by the gel filtration equilibrium dialysis technique. Per subunit of yeast phosphofructokinase two molecules of MgATP are bound in the absence of fructose-6-phosphate, one to a high-affinity and one to a low-affinity site. The experimental data were compared with a kinetic model of yeast phosphofructokinase as described by Freyer et al. [3].

UI	MeSH Term	Description	Entries
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D008970	Molecular Weight	The sum of the weight of all the atoms in a molecule.	Molecular Weights,Weight, Molecular,Weights, Molecular
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
