WebMay 17, 2011 · DinB (DNA Pol IV) is a translesion (TLS) DNA polymerase, which inserts a nucleotide opposite an otherwise replication-stalling N2-dG lesion in vitro, and confers resistance to nitrofurazone (NFZ), a compound that forms these lesions in vivo. DinB is also known to be part of the cellular response to alkylation DNA damage. Yet it is not known if … WebAug 1, 1999 · In Escherichia coli, the dinB gene is required for the SOS-induced λ untargeted mutagenesis pathway and confers a mutator phenotype to the cell when the gene product is overexpressed.

WebDinB is the only Y-family DNA polymerase that is conserved throughout all domains of life, although S. cerevisiae apparently lacks a DinB ortholog [8,50]. In non-SOS conditions, DinB is expressed at approximately 250 molecules per cell; however, the number of DinB molecules increases by approximately 10-fold under SOS-induced conditions [ 51 ]. WebDeletion of dinB from both chromosome and plasmid resulted in a four- to fivefold decrease in the rate of frameshift and base substitution mutations in a dnaE mutS double mutant background. This reduction indicates that most mistakes in replication occur as a result of the action of the auxiliary rather than the replicative polymerase in this ...
