A mathematical model was developed to describe the physiological co-regulation of two
Pseudomonasσ54-dependent promoter/regulator systems, Pu/XylR and Po/DmpR of …

Regulation of transcription by the form of RNA polymerase that contains σ N involves
activation at a distance by activators bound to sites located far upstream of the transcription …

Prokaryotes are the major source of biological diversity on earth. This is not simply because
of the large number of species present, or because of their diverse growth conditions and …

Members of the Gram-negative bacterial genus Pseudomonas are ubiquitous in soil and
water ecosystems. Amongst amino acids, arginine metabolism, especially, is key in …

Abstract The XylR/Pu regulatory node of the m-xylene biodegradation pathway of
Pseudomonas putida mt-2 is one of the most intricate cases of processing internal and …

The extant layout of the σ54 promoter Pu, harboured by the catabolic TOL plasmid, pWW0,
of Pseudomonas putida is one of the most complex instances of endogenous and …

The degradation of monocyclic aromatic hydrocarbons by bacteria is a highly regulated
process that takes place under defined environmental conditions. The catabolic pathways …

Sigma factor σ54 has a distinct modus operandi for mediating the activation of bacterial RNA
polymerase (RNAP) at promoter recognition motifs 12 and 24 bp upstream from transcription …

Cyanobacteria are a diverse group of photosynthetic gram-negative bacteria able to tap into
virtually unlimited solar energy supplies and convert it into chemical energy and biomass …

This thesis analyzes the function of the regulatory elements and the activation of $\sigma\sp
{54} $-dependent transcription of the stress-induced phage shock protein (psp) operon …
