Asymmetric/Biological Unit(hide GO term definitions)

Chain A (BTUB_ECOLI | P06129)

molecular function
	GO:0015235	cobalamin transporter activity	Enables the directed movement of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom, into, out of or within a cell.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0015288	porin activity	Catalysis of the transfer of substances, sized less than 1000 Da, from one side of the membrane to the other. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria.
	GO:0004872	receptor activity	Combining with an extracellular or intracellular messenger to initiate a change in cell activity.
biological process
	GO:0015889	cobalamin transport	The directed movement of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0006811	ion transport	The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0055085	transmembrane transport	The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other
	GO:0006810	transport	The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
	GO:0009279	cell outer membrane	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:0016021	integral component of membrane	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.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0046930	pore complex	Any small opening in a membrane that allows the passage of gases and/or liquids.

Chain B (TONB_ECOLI | P02929)

molecular function
	GO:0031992	energy transducer activity	The biological transducer activity that accepts energy and converts it to another form, often by transfer to another molecule within the cell.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0015343	siderophore transmembrane transporter activity	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).
biological process
	GO:0043213	bacteriocin transport	The directed movement of a bacteriocin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Bacteriocins are a group of antibiotics produced by bacteria and are encoded by a group of naturally occurring plasmids, e.g. Col E1. Bacteriocins are toxic to bacteria closely related to the bacteriocin producing strain.
	GO:0015889	cobalamin transport	The directed movement of cobalamin (vitamin B12), a water-soluble vitamin characterized by possession of a corrin nucleus containing a cobalt atom, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0042914	colicin transport	The directed movement of a colicin into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Colicins are a group of antibiotics produced by E. coli and related species that are encoded by a group of naturally occurring plasmids, e.g. Col E1.
	GO:0015031	protein transport	The directed movement of proteins into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
	GO:0044718	siderophore transmembrane transport	The directed movement of siderophores, low molecular weight Fe(III)-chelating substances, from one side of a membrane to the other, by means of some agent such as a transporter or pore.
	GO:0015891	siderophore transport	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:0006810	transport	The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
	GO:0016021	integral component of membrane	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.
	GO:0031233	intrinsic component of external side of plasma membrane	The component of a plasma membrane consisting of gene products and protein complexes that penetrate the external side of the plasma membrane only, either directly or via some covalently attached hydrophobic anchor.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0030288	outer membrane-bounded periplasmic space	The region between the inner (cytoplasmic or plasma) membrane and outer membrane of organisms with two membranes such as Gram negative bacteria. These periplasmic spaces are relatively thick and contain a thin peptidoglycan layer (PGL), also referred to as a thin cell wall.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
