Chain A (OMPF_ECOLI | P02931)

molecular function
	GO:0042912	colicin transmembrane transporter activity	Enables the transfer of a colicin from one side of a membrane to the other. 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:0015238	drug transmembrane transporter activity	Enables the directed movement of a drug from one side of a membrane to the other. A drug is any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease.
	GO:0015075	ion transmembrane transporter activity	Enables the transfer of an ion from one side of a membrane to the other.
	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.
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:0006855	drug transmembrane transport	The process in which a drug is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
	GO:0034220	ion transmembrane transport	A process in which an ion is transported from one side of a membrane to the other 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: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.
