Abstract

The formation of the division septum has been well characterized and the majority of the genes involved have been shown to map to the cluster. One exception is , which lies at 20 minutes, immediately downstream of the global response regulatory gene, . The promoter for has not yet been assigned. Here, it is reported that is transcribed from two promoters; the first is located within the reading frame and is dispensable whilst the second is essential and corresponds to , previously characterized as an SOS promoter regulated by LexA. is the first essential gene to be described that is controlled by an SOS-inducible promoter. A possible mechanism by which may be activated in minus strains, or in strains with uncleavable LexA, is discussed.
