Abstract

PBSX is a phage-like bacteriocin (phibacin) of Bacillus subtilis 168. Lysogeny is maintained by the PBSX-encoded repressor, Xre. The Xre protein was overproduced in Escherichia coli and isolated by affinity chromatography. Gel retardation and DNase I footprinting studies indicated that Xre binds to four sites close to its own gene. These sites overlap putative promoters for xre and a divergent transcriptional unit, containing the middle genes.
