In Escherichia coli, the ATP-bound form of DnaA (ATP–DnaA) promotes replication initiation. During replication, the bound ATP is hydrolyzed to ADP to yield the ADP-bound form (ADP–DnaA), which is inactive for initiation. The chromosomal site DARS

AbrB is a global transcriptional regulator of Bacillus subtilis that represses the expression of many genes during exponential growth. Here, we demonstrate that AbrB and its homolog Abh bind to hundreds of sites throughout the entire B. subtilis geno
