Two-component signal transduction in Synechocystis sp. PCC 6803 under phosphate limitation: role of acetyl phosphate.
The two-component signal transduction, which typically consists of a histidine kinase and a response regulator, is used by bacterial cells to sense changes in their environment. Previously, the SphS-SphR histidine kinase and response regulator pair of phosphate sensing signal transduction has been identified in Synechocystis sp. PCC 6803. In addition, some response regulators in bacteria have b...
متن کاملButanol tolerance regulated by a two-component response regulator Slr1037 in photosynthetic Synechocystis sp. PCC 6803
BACKGROUND Butanol production directly from CO2 in photosynthetic cyanobacteria is restricted by the high toxicity of butanol to the hosts. In previous studies, we have found that a few two-component signal transduction systems (TCSTSs) were differentially regulated in Synechocystis sp. PCC 6803 after butanol treatment. RESULTS To explore regulatory mechanisms of butanol tolerance, in this wo...
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 کاملA Novel “Four-component” Two-component Signal Transduction Mechanism Regulates Developmental Progression in Myxococcus xanthus*
Histidine-aspartate phosphorelays are employed by two-component signal transduction family proteins to mediate responses to specific signals or stimuli in microorganisms and plants. The RedCDEF proteins constitute a novel signaling system in which four two-component proteins comprising a histidine kinase, a histidine-kinase like protein, and two response regulators function together to regulate...
متن کاملTwo-component signal transduction in Enterococcus faecalis.
Enterococci are gram-positive constituents of the normal human microflora, typically colonizing the intestinal tract and skin (34, 47). However, these organisms are capable of causing disease as opportunistic pathogens, mainly in immunocompromised patients (35, 58). The problem of enterococcal infection has been aggravated by the emergence in the past decade of multiple antibiotic resistance, w...
