Enzyme classification and Gene Ontology terms linked to this protein.

8 GO

Gene Ontology (GO)

8
  • 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:0019867 The external membrane of Gram-negative bacteria or certain organelles such as mitochondria and chloroplasts; freely permeable to most ions and metabolites.
  • 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: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:0007166 The series of molecular signals initiated by an extracellular ligand binding to a receptor located on the cell surface. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
  • 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: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).
