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|21169496]increased sensitivity to a narrow spectrum of cephalosporin antibiotics [Pubmed|21169496]disruption of the corresponding gene in B. anthracis results in a mutator phenotype [Pubmed|21205011]The protein
Catalyzed reaction/ biological activity
5'-3' exonuclease activity at the 5' termini and at nicks of double-stranded DNA [Pubmed|23491602]the enzymatic activity of WalJ directly or indirectly affects cell wall metabolism and is required for accurate coordination of [SW|cell division] with DNA replication [Pubmed|21169496]Protein family
