Abstract

Except for the main porin proteins OmpC and OmpF there exist the membrane proteins participating in the transport of specific substrates: phosphates, nucleosides, iron, vitamin B12, maltose and maltodextrins, that also play the role of phage receptors. Some phages use as receptors the porins determined by the genes of lambdoid prophages. LamB protein that serves receptor for phage lambda exposes the amino acids sequence on the outer surface of membranes that participates in phage adsorption. The sequence is similar to tetrapeptide of fibronectin responsible for binding with the surface of cellular receptor in eucaryotes.
