Introduction to Bacterial Signal Transduction Networks,roduce three such networks in . that were clarified using a DNA microarray: a PhoQ/PhoP system that senses extracellular Mg. and controls the gene expression for adaptation to environmental Mg. deprivation (Mg. stimulon); an, EvgS/EvgA signal transduction system that activates expression of multiple

The PhoQ/PhoP Regulatory Network of ,,aptation to low Mg. environments by governing the expression and/or activity of Mg. transporters and of enzymes modifying the Mg.-binding sites on the bacterial cell surface. The regulator PhoP modifies expression of ≈3% of the . genes in response to the periplasmic Mg. concentration detected by the

Structural Basis of the Signal Transduction in the Two-Component System,mental change, the signal is transduced from HK to RR through phosphoryl transfer. At the first stage of structural biology of TCS, crystallographic and NMR analyses of domain blocks revealed the folds and the remarkable regions of sensor, dimerization and catalytic domains of HK and receiver and ef

Small RNAs Controlled by Two-Component Systems,el. It has been recently recognized that prokaryotes also regulate many genes and operons at a posttranscriptional level with the participation of small, noncoding RNAs which serve to control translation initiation and stability of target mRNAs, either directly by establishing antisense interactions

Two-Component Signaling and Gram Negative Envelope Stress Response Systems, be compartmentalized into the cytoplasmic and extracytoplasmic (envelope) stress responses. The extracytoplasmic stress response monitors the integrity of the envelope, which consists of the outer membrane (OM), inner membrane (IM) and the periplasm. The OM is an atypical membrane in that it is asy
