May be required for repair of DNA lesions formed after exposure to oxidative stress. Induced by bleomycin, methyl methane sulphonate and hydrogen peroxide, which are known to induce oxidative lesions in DNA. Also induced by bacterial flagellin, which is known to elicit plant defense responses and a rapid oxidative burst, and by xylanase. Belongs to the DNA repair metallo-beta-lactamase (DRMBL) family.
