[https://www.uniprot.org/uniprot/OMPA_ECOLI OMPA_ECOLI] Required for the action of colicins K and L and for the stabilization of mating aggregates in conjugation. Serves as a receptor for a number of T-even like phages. Also acts as a porin with low permeability that allows slow penetration of small solutes.

== Publication Abstract from PubMed ==
 +
We have determined the three-dimensional fold of the 19 kDa (177 residues) transmembrane domain of the outer membrane protein A of Escherichia coli in dodecylphosphocholine (DPC) micelles in solution using heteronuclear NMR. The structure consists of an eight-stranded beta-barrel connected by tight turns on the periplasmic side and larger mobile loops on the extracellular side. The solution structure of the barrel in DPC micelles is similar to that in n-octyltetraoxyethylene (C(8)E(4)) micelles determined by X-ray diffraction. Moreover, data from NMR dynamic experiments reveal a gradient of conformational flexibility in the structure that may contribute to the membrane channel function of this protein.
