6-phosphofructokinase complex Overview

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code.


Summary
Catalyzes the phosphorylation of fructose 6-phosphate to fructose 1,6-bisphosphate in the presence of MgATP, the first irreversible step for glycolysis. The enzyme is stablilized in the presence of Fructose 6-P and exhibits cooperative binding of Fructose 6-P. Its activity is controlled by many allosteric activators and inhibitors (including ATP), showing its crucial role in regulation of glycolytic flux. The enzyme can exist in either the active R-state or inhibited T-state. The effectors either modulate the affinity of Pfk for Fructose 6-P or overcome inhibitory effects. Pfk is an octamer composed of 4 alpha and 4 beta subunits.
GO Slim Terms

The yeast GO Slim terms are higher level terms that best represent the major S. cerevisiae biological processes, functions, and cellular components. The GO Slim terms listed here are the broader parent terms for the specific terms to which this gene product is annotated, and thus represent the more general processes, functions, and components in which it is involved.
