FunFam 80781: Phosphate regulon sensor protein

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 3 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Phosphorelay sensor kinase activity GO:0000155
Catalysis of the phosphorylation of a histidine residue in response to detection of an extracellular signal such as a chemical ligand or change in environment, to initiate a change in cell state or activity. The two-component sensor is a histidine kinase that autophosphorylates a histidine residue in its active site. The phosphate is then transferred to an aspartate residue in a downstream response regulator, to trigger a response.

Phosphorelay sensor kinase activity GO:0000155
Catalysis of the phosphorylation of a histidine residue in response to detection of an extracellular signal such as a chemical ligand or change in environment, to initiate a change in cell state or activity. The two-component sensor is a histidine kinase that autophosphorylates a histidine residue in its active site. The phosphate is then transferred to an aspartate residue in a downstream response regulator, to trigger a response.
1 P08400 (/IDA)
Phosphoprotein phosphatase activity GO:0004721
Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate. Together with protein kinases, these enzymes control the state of phosphorylation of cell proteins and thereby provide an important mechanism for regulating cellular activity.
1 P08400 (/IMP)

There are 6 GO terms relating to "biological process"

GO Term Annotations Evidence
Phosphorelay signal transduction system GO:0000160
A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins.
2 Q48BQ3 (/ISS) Q87U37 (/ISS)
Phosphorelay signal transduction system GO:0000160
A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins.
1 P08400 (/IDA)
Phosphate-containing compound metabolic process GO:0006796
The chemical reactions and pathways involving the phosphate group, the anion or salt of any phosphoric acid.
1 Q87U37 (/ISS)
Phosphate ion transport GO:0006817
The directed movement of phosphate into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 Q87U37 (/ISS)
Cellular response to phosphate starvation GO:0016036
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of deprivation of phosphate.
1 P08400 (/IEP)
Protein autophosphorylation GO:0046777
The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).
1 P08400 (/IDA)

GO Term Annotations Evidence
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 P08400 (/IDA)
Integral component of membrane GO:0016021
The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
