The Bacillus subtilis tryptophan biosynthetic genes are regulated by TRAP. Radiographic crystallography indicates that the TRAP complex contains 11 identical subunits arranged in a doughnut-like structure termed the beta-wheel. The trpEDCFBA operon i

The Escherichia coli NsrR protein is a nitric oxide-sensitive repressor of transcription. The NsrR-binding site is predicted to comprise two copies of an 11 bp motif arranged as an inverted repeat with 1 bp spacing. By mutagenesis we confirmed that b

Summary In transcription initiation, all RNA polymerase molecules bound to a promoter have been conventionally supposed to proceed into elongation of transcript. However, for Escherichia coli RNA polymerase, evidence has been accumulated for a view t

Transcription from the bop promoter in the haloarchaeon Halobacterium NRC-1, is highly induced under oxygen-limiting conditions. A DNA gyrase inhibitor, novobiocin, was previously shown to block bop gene induction and suggested that DNA supercoiling

We describe the use of time-lapse fluorescence microscopy to visualize the movement of the DNA replication origin and terminus regions on the Bacillus subtilis chromosome during the course of the cell cycle. The origin and terminus regions were tagge

A combination of deletion analysis and random mutagenesis was used to identify regulatory elements in Pmcb, the stationary phase-induced promoter of the mcb operon. Our results indicate that Pmcb is controlled by at least three different factors, two

Summary The P2 ogr gene encodes a 72–amino–acid protein required for P2 late gene expression. This gene was defined originally by a class of compensatory mutations which overcome the block to P2 late transcription imposed by a host mutation, rpoA

International audience; A gene bank of Azospirillum lipoferum Br17 constructed in the vector lambda GEM11 was screened with a Bradyrhizobium japonicum nifA gene probe. A 7.3 kb EcoRI fragment carrying a nifA-like gene was thereby isolated and subsequ

RovA is a transcriptional activator of Yersinia invasin, an outer membrane protein involved in bacterial attachment and invasion across the intestinal epithelium. In Y. enterocolitica, a rovA mutant is attenuated for virulence compared with either wi

Expression of the Bacillus subtilis tryptophan biosynthetic genes trpEDCFBA and trpG, as well as a putative tryptophan transport gene (trpP), are regulated in response to tryptophan by the trp RNA-binding attenuation protein (TRAP). TRAP regulates ex
