FunFam 7264: BarA sensory histidine kinase

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 5 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.
1 P0AEC5 (/IDA)
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 Q9KPC0 (/ISS)
Phosphorelay response regulator activity GO:0000156
Responds to a phosphorelay sensor to initiate a change in cell state or activity. The activity of the response regulator is regulated by transfer of a phosphate from a histidine residue in the sensor, to an aspartate residue in the response regulator. Many but not all response regulators act as transcriptional regulators to elicit a response.
1 Q9KPC0 (/ISS)
Signal transducer activity GO:0004871
Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.
1 Q54RR8 (/IDA)
Histidine phosphotransfer kinase activity GO:0009927
Serves as a phospho-His intermediate enabling the transfer of phospho group between a hybrid kinase and a response regulator.

There are 13 GO terms relating to "biological process"

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 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 P0AEC5 (/IDA) Q54RR8 (/IDA)
Positive regulation of secondary metabolite biosynthetic process GO:1900378
Any process that activates or increases the frequency, rate or extent of secondary metabolite biosynthetic process.
2 G3XD98 (/IMP) O31138 (/IMP)
Positive regulation of cell motility GO:2000147
Any process that activates or increases the frequency, rate or extent of cell motility.
2 G3XD98 (/IMP) O31138 (/IMP)
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 Q9KPC0 (/ISS)
Protein phosphorylation GO:0006468
The process of introducing a phosphate group on to a protein.
1 P0AEC5 (/IDA)
Sporulation resulting in formation of a cellular spore GO:0030435
The process in which a relatively unspecialized cell acquires the specialized features of a cellular spore, a cell form that can be used for dissemination, for survival of adverse conditions because of its heat and dessication resistance, and/or for reproduction.
1 Q54RR8 (/IGI)
Sorocarp development GO:0030587
The process whose specific outcome is the progression of the sorocarp over time, from its formation to the mature structure. The process begins with the aggregation of individual cells and ends with the mature sorocarp. The sorocarp is a structure containing a spore-bearing sorus that sits on top of a stalk. An example of this process is found in Dictyostelium discoideum.
1 Q54RR8 (/IMP)
Sorocarp morphogenesis GO:0031288
The process in which the sorocarp is generated and organized. An example of this process is found in Dictyostelium discoideum.
1 Q54RR8 (/IMP)
Response to hydrogen peroxide GO:0042542
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a hydrogen peroxide (H2O2) stimulus.
1 P0AEC5 (/IMP)
CAMP metabolic process GO:0046058
The chemical reactions and pathways involving the nucleotide cAMP (cyclic AMP, adenosine 3',5'-cyclophosphate).
1 Q54RR8 (/IMP)
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 P0AEC5 (/IDA)
Positive regulation of chemotaxis to cAMP by DIF-2 GO:0061128
Any process that increases the rate, frequency, or extent of directed movement of a motile cell or organism up a concentration gradient of 3',5'-cAMP by the action of DIF-2. DIF-2 is a chlorinated alkylphenone.
1 Q54RR8 (/IMP)
Cellular response to organic substance GO:0071310
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 an organic substance stimulus.

GO Term Annotations Evidence
Intracellular GO:0005622
The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
1 Q54RR8 (/IDA)
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.
