Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Catalyzes the phosphorylation of D-fructose 6-phosphate to fructose 1,6-bisphosphate by ATP, the first committing step of glycolysis.1 Publication

Miscellaneous

Only 10% of the activity present in the wild-type strain is phosphofructokinase-2.
This enzyme is not to be confused with 6-phosphofructo-2-kinase which is also called phosphofructokinase 2.
E.coli has two 6-phosphofructokinases enzymes.

<p>This subsection of the <a href="http://www.uniprot.org/help/function%5Fsection">Function</a> section describes the catalytic activity of an enzyme, i.e. a chemical reaction that the enzyme catalyzes.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityi

<p>This subsection of the 'Function' section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

Allosterically inhibited by ATP. Allosteric ATP-binding requires the presence of the substrate ATP. Inhibited by monovalent cations with ionic radii larger than Na+ (e.g. K+, Cs+). The monovalent cations increase the affinity of the allosteric site for ATP. PFK-2 is sensitive to inhibition by fructose 1,6-diphosphate.2 Publications

    This protein is involved in step 3 of the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose.
    Proteins known to be involved in the 4 steps of the subpathway in this organism are:
    1. no protein annotated in this organism
    2. Glucose-6-phosphate isomerase (pgi), Glucose-6-phosphate isomerase (pgi)
    3. ATP-dependent 6-phosphofructokinase (pfkA), ATP-dependent 6-phosphofructokinase isozyme 1 (pfkA), ATP-dependent 6-phosphofructokinase isozyme 2 (pfkB)
    4. Fructose-bisphosphate aldolase class 2 (fbaA), Fructose-bisphosphate aldolase (fbaA)
    This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-glyceraldehyde 3-phosphate and glycerone phosphate from D-glucose, the pathway glycolysis and in Carbohydrate degradation.

    <p>This subsection of the 'Entry information' section provides a mnemonic identifier for a UniProtKB entry, but it is not a stable identifier. Each reviewed entry is assigned a unique entry name upon integration into UniProtKB/Swiss-Prot.<p><a href='/help/entry_name' target='_top'>More...</a></p>Entry nameiPFKB_ECOLI
    <p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P06999
    Secondary accession number(s): P78065, P78260
    <p>This subsection of the 'Entry information' section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification ('Last modified'). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical%5Fand%5Fisoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: April 1, 1988

    This is version 172 of the entry and version 2 of the sequence. See complete history.
    <p>This subsection of the 'Entry information' section indicates whether the entry has been manually annotated and reviewed by UniProtKB curators or not, in other words, if the entry belongs to the Swiss-Prot section of UniProtKB (<strong>reviewed</strong>) or to the computer-annotated TrEMBL section (<strong>unreviewed</strong>).<p><a href='/help/entry_status' target='_top'>More...</a></p>Entry statusiReviewed (UniProtKB/Swiss-Prot)
