OEP

• PFAM accession number: PF02321
• Interpro abstract (IPR003423):

  The OEP family (Outer membrane efflux protein) form trimeric channels that allow export of a variety of substrates in Gram-negative bacteria. Each member of this family is composed of two repeats. The trimeric channel is composed of a 12 stranded all beta sheet barrel that spans the outer membrane, and a long all helical barrel that spans the periplasm. Examples include the Escherichia coli TolC outer membrane protein, which is required for proper expression of outer membrane protein genes; the Rhizobium nodulation protein; and the Pseudomonas FusA protein, which is involved in resistance to fusaric acid.

• GO process: transmembrane transport (GO:0055085)
• GO function: efflux transmembrane transporter activity (GO:0015562)
