A two-component signal transduction system essential for growth of Bacillus subtilis: implications for anti-infective therapy.
A two-component signal transduction system encoded by the yycF and yycG genes is part of an operon containing three genes, yycH, yycI, and yycJ, with no known function and a gene, yycK, coding for an HtrA-like protease. This operon was transcribed during growth, and its transcription shut down as the cells approached stationary phase. This decreased transcription was not Spo0A dependent. The Ht...

متن کاملAn essential two-component signal transduction system in Mycobacterium tuberculosis.
The bacterial two-component signal transduction systems regulate adaptation processes and are likely to play a role in Mycobacterium tuberculosis physiology and pathogenesis. The previous initial characterization of an M. tuberculosis response regulator from one of these systems, mtrA-mtrB, suggested its transcriptional activation during infection of phagocytic cells. In this work, we further c...
متن کاملTwo-component signal transduction.
Most prokaryotic signal-transduction systems and a few eukaryotic pathways use phosphotransfer schemes involving two conserved components, a histidine protein kinase and a response regulator protein. The histidine protein kinase, which is regulated by environmental stimuli, autophosphorylates at a histidine residue, creating a high-energy phosphoryl group that is subsequently transferred to an ...
متن کاملFunctional characterization of WalRK: A two-component signal transduction system from Bacillus anthracis☆
Two-component signal transduction systems (TCS), consisting of a sensor histidine protein kinase and its cognate response regulator, are an important mode of environmental sensing in bacteria. Additionally, they have been found to regulate virulence determinants in several pathogens. Bacillus anthracis, the causative agent of anthrax and a bioterrorism agent, harbours 41 pairs of TCS. However, ...
