Function
Plays a central regulatory role in DNA repair and protection pathways in response to radiation stress (PubMed:12804570, PubMed:22051194). Acts as a site-specific metalloprotease that cleaves and inactivates the repressor protein DdrO, resulting in induced expression of genes required for DNA repair and cell survival after exposure to radiation (By similarity). Regulates the expression of dozens of proteins from different pathways, including the important DNA repair proteins RecA and PprA (PubMed:12399492, PubMed:12804570, PubMed:22051194). Binds to the promoters of recA and pprA (PubMed:22051194).
