DNA-binding and peroxide stress resistance protein YaaA

UniProtKB accession:  P0A8I3

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in the cellular response to hydrogen peroxide (H(2)O(2)) stress (PubMed:21378183). During H(2)O(2) stress, prevents oxidative damage to both DNA and proteins by diminishing the amount of unincorporated iron within the cell (PubMed:21378183). Binds double-stranded, bulge-containing, bubble duplex and Holliday junction DNA with approximately equal affinity and ssDNA with lower affinity (PubMed:32796037). DNA binding shows positive cooperativity (PubMed:32796037). Cofitness analysis suggests it might be involved in DNA repair pathways (PubMed:32796037) (Probable).
