Abstract excerpt
The endogenous tonB gene of Escherichia coli was used as a target for spontaneous deletion mutations which were isolated from ruvAB-, recG-, and ruvC- cells. The rates of tonB mutation were essentially the same in ruv+, ruvAB-, recG-, and ruvC- cells. We analyzed tonB mutants by sequencing. In the ruv+, recG-, and ruvC- strains, the spectra were different from those obtained from the ruvAB- cells, where deletions...
