Abstract
We present the DNA sequence alterations due to seven lamB missense mutations yielding resistance to phages lambda and K10. They reveal five different amino acid positions in the LamB protein. Three positions (245, 247 and 249) define a new region required for phage adsorption. The two other positions (148 and 152) belong to a region where mutations to phage resistance has already been detected. These two regions are hydrophilic and could belong to turns of the protein located at the surface of the cell. All the missense mutational alterations to phage resistance sequenced in the LamB protein correspond to 10 sites located in four different segments of the polypeptide chain. We discuss their location in terms of the notion of phage receptor site and of a working model for the organization of this protein in the outer membrane of Escherichia coli.
