  • Title: The nucleoid protein H-NS facilitates chromosome DNA replication in Escherichia coli dnaA mutants.
    Author: Katayama T, Takata M, Sekimizu K.
    Journal: J Bacteriol; 1996 Oct; 178(19):5790-2. PubMed ID: 8824628.
    Abstract:
    Growth inhibition of the dnaA(Cs) mutant, which overinitiates chromosome replication, was shown to be dependent upon the nucleoid protein H-NS. [3H]thymine incorporation experiments indicated that the absence of H-NS inhibited overreplication by the dnaA(Cs) mutant. In addition, the temperature-sensitive phenotype of a dnaA46 mutant was enhanced by disruption of H-NS. These observations suggest that H-NS directly or indirectly facilitates the initiation of chromosome replication.
