This study investigates how bacterial replication forks are restarted after encountering single-strand discontinuities, showing that recombinational repair and PriA-dependent mechanisms are essential for replication restart in Bacillus subtilis.

The paper identifies SirA as a repressor that inhibits DnaD-DnaA interaction, blocking helicase recruitment during Bacillus subtilis sporulation.

The paper identifies a specific ssDNA motif in Bacillus subtilis oriC that is preferentially bound by DnaD, facilitating strand-specific helicase recruitment for bidirectional replication.
