RecBCD Prevents Bacterial Autoimmunity by Clearing Self-DNA Ends Produced During Replication Termination

Apurva A. Govande, Brooke Ramsey, Irem Ünlü…·Hoong Chuin Lim

The paper shows that RecBCD clears self-DNA ends during bacterial replication termination to prevent autoimmunity, similar to TREX1 and DBR1 in eukaryotes.

Chi hotspot control of RecBCD helicase-nuclease by long-range intramolecular signaling

Susan K. Amundsen, Andrew F. Taylor, Gerald R. Smith

The paper investigates how the Chi recombination hotspot controls the RecBCD helicase-nuclease through long-range intramolecular signaling, identifying mutations that disrupt this communication pathway.
