This paper identifies two regulatory systems involving ScoC, AbrB, and PchR that control pulcherrimin biosynthesis in Bacillus subtilis, showing their combined necessity to limit its production.

This study shows that FEN, not Pol I, is the primary 5' nuclease for RNA primer removal in B. subtilis during Okazaki fragment processing.

The paper identifies a mitomycin C-specific DNA repair pathway in Bacillus subtilis involving MrfA and MrfB, showing its conservation and adaptation to antibiotic resistance.

This paper identifies DdcA as a regulator of the bacterial DNA damage checkpoint, showing it antagonizes YneA activity independently of proteolysis, challenging the existing model of checkpoint regulation.

This study identifies cryptic protein interactions essential for DNA replication initiation by mapping interactions between DnaA, its adaptors, and the helicase in bacteria.
