RuvB protein is an important component of the RuvABC complex and plays a key role in recombinant DNA repair, especially for UV-induced damage. It helps rescue stalled DNA replication forks through replication fork reversal (RFR) . RuvB Protein, E.coli (His-SUMO) is the recombinant E. coli-derived RuvB protein, expressed by E. coli , with N-SUMO, N-6*His labeled tag.
