The Gram-negative bacterial outer membrane contains several independent, biochemically distinct transport systems for the acquisition of solutes from the environment. Three or more different classes of membrane proteins exist within the porin superfamily, that facilitate the uptake of sugars, amino acids, nucleotides, vitamins and metals. In spite of crystallographic descriptions of these protein...
To kill Escherichia coli, toxic proteins, called colicins, pass through the permeability barrier created by the outer membrane (OM) of the bacterial cell envelope. We consider a variety of different colicins, including A, B, D, E1, E3, Ia, M and N, that penetrate through the porins OmpF, FepA, BtuB, Cir and FhuA, to subsequently interact with a few targets in the periplasm, including TolA, TolB, TolC...
