>PF00365 PFK: Phosphofructokinase; InterPro: IPR000023 The enzyme-catalysed transfer of a phosphoryl group from ATP is an important reaction in a wide variety of biological processes []
One enzyme that utilises this reaction is phosphofructokinase (PFK), which catalyses the phosphorylation of fructose-6-phosphate to fructose-1,6- bisphosphate, a key regulatory step in the glycolytic pathway [, ]. PFK exists as a homotetramer in bacteria and mammals (where each monomer possesses 2 similar domains), and as an octomer in yeast (where there are 4 alpha- (PFK1) and 4 beta-chains (PFK2), the latter, like the mammalian monomers, possessing 2 similar domains []). PFK is ~300 amino acids in length, and structural studies of the bacterial enzyme have shown it comprises two similar (alpha/beta) lobes: one involved in ATP binding and the other housing both the substrate-binding site and the allosteric site (a regulatory binding site distinct from the active site, but that affects enzyme activity). The identical tetramer subunits adopt 2 different conformations: in a 'closed' state, the bound magnesium ion bridges the phosphoryl groups of the enzyme products (ADP and fructose-1,6- bisphosphate); and in an 'open' state, the magnesium ion binds only the ADP [], as the 2 products are now further apart. These conformations are thought to be successive stages of a reaction pathway that requires subunit closure to bring the 2 molecules sufficiently close to react []. Deficiency in PFK leads to glycogenosis type VII (Tauri's disease), an autosomal recessive disorder characterised by severe nausea, vomiting, muscle cramps and myoglobinuria in response to bursts of intense or vigorous exercise []. Sufferers are usually able to lead a reasonably ordinary life by learning to adjust activity levels [].; GO: 0003872 6-phosphofructokinase activity, 0006096 glycolysis, 0005945 6-phosphofructokinase complex; PDB: 3O8O_E 3OPY_H 1PFK_A 2PFK_D 1MTO_F 3U39_C 6PFK_A 4PFK_A 3PFK_A 3HNO_B ....

>cd00363 PFK Phosphofructokinase, a key regulatory enzyme in glycolysis, catalyzes the phosphorylation of fructose-6-phosphate to fructose-1,6-biphosphate
The members belong to PFK family that includes ATP- and pyrophosphate (PPi)- dependent phosphofructokinases. Some members evolved by gene duplication and thus have a large C-terminal/N-terminal extension comprising a second PFK domain. Generally, ATP-PFKs are allosteric homotetramers, and PPi-PFKs are dimeric and nonallosteric except for plant PPi-PFKs which are allosteric heterotetramers.
Members of this family that are characterized, save one, are phosphofructokinases dependent on pyrophosphate (EC 2.7.1.90) rather than ATP (EC 2.7.1.11). The exception is one of three phosphofructokinases from Streptomyces coelicolor. Family members are both bacterial and archaeal.
Members of this family are eukaryotic (with one exception) ATP-dependent 6-phosphofructokinases (EC 2.7.1.11) in which two tandem copies of the phosphofructokinase are found.

Diphosphate--fructose-6-phosphate 1-phosphotransferase catalyzes the addition of phosphate from diphosphate (PPi) to fructose 6-phosphate to give fructose 1,6-bisphosphate (EC 2.7.1.90). The enzyme is also known as pyrophosphate-dependent phosphofructokinase. The usage of PPi-dependent enzymes in glycolysis presumably frees up ATP for other processes. TIGR02482 represents the ATP-dependent 6-phosphofructokinase enzyme contained within Pfam pfam00365: Phosphofructokinase. This model hits primarily bacterial, plant alpha, and plant beta sequences.

The members belong to a subfamily of the PFKA family (cd00363) and include pyrophosphate-dependent phosphofructokinases. These are found in bacteria as well as plants. These may be dimeric nonallosteric enzymes as in bacteria or allosteric heterotetramers as in plants.
Flavodoxins are small redox-active proteins with a flavin mononucleotide (FMN) prosthetic group. They can act in nitrogen fixation by nitrogenase, in sulfite reduction, and light-dependent NADP+ reduction in during photosynthesis, among other roles. This model describes the long chain type, typical for nitrogen fixation but associated with pyruvate formate-lyase activation and cobalamin-dependent methionine synthase activity in E. coli.
