Degenerate PCR probes were used to amplify gene fragments encoding the catalytic
domain of sigma54-dependent transcription activators. The procedure should be widely …

The ptsN gene of Pseudomonas putida encodes IIANtr, a protein of the phosphoenol
pyruvate: sugar phosphotransferase (PTS) system which is required for the C source …

Bacterial sigma (σ) factors confer gene specificity upon the RNA polymerase, the central
enzyme that catalyses gene transcription. The binding of the alternative σ factor σ54 confers …

Extracytoplasmic function (ECF) sigma factors control expression of large numbers of genes
in bacteria. Most ECF sigma factors are inhibited by antisigma proteins, with inhibition being …

The association of a sigma factor (sigma) with RNA polymerase in bacteria determines its
specificity of promoter utilization. To identify amino acid residues in sigma E from Bacillus …

Bacterial enhancer binding proteins (bEBPs) are transcriptional activators that assemble as
hexameric rings in their active forms and utilize ATP hydrolysis to remodel the conformation …

We describe here the functional characterization of the putative flgM gene of Pseudomonas
aeruginosa. FlgM of P. aeruginosa is most similar to FlgM of Vibrio parahaemolyticus. A …

The σ factors are the key regulators of bacterial transcription initiation. Through direct read-
out of promoter DNA sequence, they recruit the core RNA polymerase to sites of initiation …

The gene (rpoD) encoding the principal α factor of Pseudomonas putida (Pp) was cloned
and sequenced. The amino-acid sequence deduced from the nucleotide sequence of rpoD …

Alternative sigma (σ) factors govern expression of bacterial genes in response to diverse
environmental signals. In Pseudomonas aeruginosa σPvdS directs expression of genes for …
