Allosteric mechanism of signal transduction in the two-component system histidine kinase PhoQ
Transmembrane signaling proteins couple extracytosolic sensors to cytosolic effectors. Here, we examine how binding of Mg2+ to the sensor domain of an E. coli two component histidine kinase (HK), PhoQ, modulates its cytoplasmic kinase domain.

Architecture of a complete Bce-type antimicrobial peptide resistance module
Gram-positive bacteria synthesize and secrete antimicrobial peptides that target the essential process of peptidoglycan synthesis. These antimicrobial peptides not only regulate the dynamics of microbial communities but are also of clinical importance as

Novel Family of Sensor Histidine Kinase Genes in Arabidopsis thaliana [PDF]
We identified three novel, highly homologous, sensor histidine kinases that possibly function in the plasma membrane of Arabidopsis thaliana, i.e. AHK2, 3 and 4. While AHK2 and 3 are expressed in several organs, AHK4 is mainly expressed in roots. AHK3 suppresses a sensor histidine kinase mutant of yeast.

Structure of the entire cytoplasmic portion of a sensor histidine‐kinase protein [PDF]
The large majority of histidine kinases (HKs) are multifunctional enzymes having autokinase, phosphotransfer and phosphatase activities, and most of these are transmembrane sensor proteins. Sensor HKs possess conserved cytoplasmic phosphorylation and ATP-binding kinase domains.

Feedback Control of a Two-Component Signaling System by an Fe-S-Binding Receiver Domain
Two-component signaling systems (TCSs) function to detect environmental cues and transduce this information into a change in transcription. In its simplest form, TCS-dependent regulation of transcription entails phosphoryl-transfer from a sensory ...

Role of a sensor histidine kinase ChiS of Vibrio cholerae in pathogenesis [PDF]
Vibrio cholera survival in an aquatic environment depends on chitin utilization pathway that requires two factors, chitin binding protein and chitinases. The chitinases and the chitin utilization pathway are regulated by a two-component sensor histidine kinase ChiS in V. cholerae.

Structure and function of HWE/HisKA2-family sensor histidine kinases [PDF]
Sensor histidine kinases regulate adaptive cellular responses to changes in the chemical or physical state of the environment. HWE/HisKA2-family kinases comprise a subset of histidine kinases that is defined by unique sequence motifs in both the catalytic and non-catalytic regions.
