In vivo definition of an archaeal promoter.

abstract：:Escherichia coli contains 30 two-component systems (TCSs), each consisting of a histidine kinase and a response regulator. Whereas most TCSs are well characterized in this model organism, little is known about the YpdA/YpdB system. To identify YpdB-regulated genes, we compared the transcriptomes of E. coli cells overp...
