WebMar 15, 2024 · A bacterium’s ability to properly sense and respond to its internal and external environments is crucial for the survival of the bacterium. As such, alphaproteobacteria like Agrobacterium tumefaciens have evolved key two-component systems and phosphorelays to quickly adapt to these changes. Several of these key … WebApr 12, 2024 · Bacterial two-component regulatory systems (TCSs) mediate signal transduction by transferring phosphoryl groups between sensor kinase and response regulator proteins, sometimes using intermediary histidine-phosphotransferase (Hpt) domains to form multistep phosphorelays.
