Pathway Description
BaeSR Two-Component Signal Transduction System
Escherichia coli
Protein Pathway
In E.coli K-12, two component systems (TCSs) are responsible for sensing and response to changes in environmental conditions. Sensor kinase response environmental signals by auto-phosphorylate on membrane, which transfer a phosphoryl group to a response regulator (RR) for activation. Signal transduction histidine-protein kinase (BaeS) is sensor kinase and transcriptional regulatory protein (BaeR) is the response regulator in the TCSs. BaeR overexpression may lead to greater resistance to novobiocin and deoxycholate.
