| Abstract |
Analysis of the nucleotide sequence of an Escherichia coli colicin S4 determinant revealed 76% identity to the pore-forming domain of the colicin A protein, 77% identity to the colicin A immunity protein, and 82% identity to the colicin A lysis protein. The N-terminal region, which is responsible for the Tol-dependent uptake of colicin S4, has 94% identity to the N-terminal region of colicin K. By contrast, the predicted receptor binding domain shows no sequence similarities to other colicins. Mutants that lacked the OmpW protein were resistant to colicin S4. |
