Functional Annotations

Enzyme classification and Gene Ontology terms linked to this protein.

10 GO

Gene Ontology (GO)

10
  • GO:0009279 A lipid bilayer that forms the outermost membrane of the cell envelope; enriched in polysaccharide and protein; the outer leaflet of the membrane contains specific lipopolysaccharide structures.
  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • GO:0015344 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: siderophore-iron(ferrioxamine)(out) + H+(out) = siderophore-iron(ferrioxamine)(in) + H+(in).
  • GO:0016987 Sigma factors act as the promoter specificity subunit of eubacterial and plant plastid multisubunit RNA polymerases, whose core subunit composition is often described as alpha(2)-beta-beta-prime. Although sigma does not bind DNA on its own, when combined with the core to form the holoenzyme, the sigma factor binds specifically to promoter elements. The sigma subunit is released once elongation begins.
  • GO:0038023 Receiving a signal and transmitting it in the cell to initiate a change in cell activity. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.
  • GO:0034756 Any process that modulates the frequency, rate or extent of the directed movement of iron ions (Fe) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0015891 The directed movement of siderophores, low molecular weight Fe(III)-chelating substances, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
  • GO:0033214 A process in which iron (Fe3+) is solubilized by ferric iron-specific chelators, known as siderophores is imported into the cell by transmembrane transport or endocytosis.
  • GO:0019867 The external membrane of Gram-negative bacteria or certain organelles such as mitochondria and chloroplasts; freely permeable to most ions and metabolites.
  • GO:0015343 Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: siderophore-iron(out) + H+(out) = siderophore-iron(in) + H+(in).

Ligand evidence

Ligands grouped by evidence source. PDB ligands keep the source crystal visible, and loaded crystals can be opened directly in the structure viewer.

56 records

Structural evidence inferred from similar proteins. The source crystal indicates where the ligand was observed; the UniProt column identifies the homologous protein carrying that ligand.
