Phosphofructose kinase
Phosphofructokinase-1 (PFK-1) is one of the most important regulatory enzymes (EC 2.7.1.11) of glycolysis. It is an allosteric enzyme made of 4 subunits and controlled by many activators and inhibitors. PFK-1 catalyzes the important "committed" step of glycolysis, the conversion of fructose 6-phosphate and ATP to fructose 1,6-bisphosphate and ADP. Glycolysis is the foundation for respiration… WebIn growing cells, the citrate exported from mitochondria into the cytosol suppresses glycolysis at the level of phosphofructose kinase 1 (PFK-1). This partial suppression of PFK-1 may be adaptive for cell growth by allowing a greater amount of glucose-6-phosphate to be diverted into nucleotide biosynthesis and glycosylation reactions.

Apparently ATP allosterically regulates PFK, meaning it inhibits the enzyme by decreasing its affinity for F6P.
