Constitutive expression of the S. typhimurium histidine operon causes multiple phenotypic changes including strong flamentation. However, the SOS regulatory network is not involved in the inhibition of cell division. The possibility of SOS‐ independent activation of sulA gene transcription has been ruled out using sulA‐lacZ fusions. These results suggest that existence of a pathway of division inhibition unrelated to sulA and not regulated by the SOS system.
