The tdh and serA operons of Escherichia coli: mutational analysis of the regulatory elements of leucine-responsive genes.

abstract：:The Streptomyces coelicolor absA two-component system was initially identified through analysis of mutations in the sensor kinase absA1 that caused inhibition of all four antibiotics synthesized by this strain. Previous genetic analysis had suggested that the phosphorylated form of AbsA2 acted as a negative regulator ...
