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
