This gene is a member of the following regulons

The gene

Basic information

  • Locus tag: BSU40370

Phenotypes of a mutant

  • the mutant divides over unsegregated chromosomes more frequently than wild-type cells, and this phenotype is exacerbated when DNA replication is inhibited PubMed
  • increased sensitivity to a narrow spectrum of cephalosporin antibiotics PubMed
  • disruption of the corresponding gene in B. anthracis results in a mutator phenotype PubMed
