| Abstract: | Major outer membrane components which determine the structure and the barrier function of membrane Gram-negative bacteria are receptors for many bacteriophages. LPS--the major component of the outer membrane of Enterobacteria can be used by some phages with wide host range specificity. The other component of the outer membrane frequently include phage receptor component is OmpA protein. OmpA protein different areas can be used as receptors for different phages T--even group. A large group of phage receptors compose porin proteins, which are discovered in 32 species of bacteria. The synthesis of major porin proteins, which a receptor for several phages, are regulated by sufficiently complex system of some genes. These genes are sensitive to the changes of environment. |
