Function
PFKA1_YEAST Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.[HAMAP-Rule:MF_03184][1] [2] [3] [4] [5] [6] [7] [8]
Publication Abstract from PubMed
Phosphofructokinase 1 (PFK) is a multisubunit allosteric enzyme that catalyzes the principal regulatory step in glycolysis-the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate by ATP. The activity of eukaryotic PFK is modulated by a number of effectors in response to the cell's needs for energy and building blocks for biosynthesis. The crystal structures of eukaryotic PFKs-from Saccharomyces cerevisiae and rabbit skeletal muscle-demonstrate how successive gene duplications and fusion are reflected in the protein structure and how they allow the evolution of new functionalities. The basic framework inherited from prokaryotes is conserved, and additional levels of structural and functional complexity have evolved around it. Analysis of protein-ligand complexes has shown how PFK is activated by fructose 2,6-bisphosphate (a powerful PFK effector found only in eukaryotes) and reveals a novel nucleotide binding site. Crystallographic results have been used as the basis for structure-based effector design.
