In this study, it was found that Bacillus subtilis HU (HBsu) plays a crucial role in driving DnaA-dependent initiation of DNA replication at the chromosome origin, revealing the importance of HU in replication initiation and other cellular functions.
The prokaryotic nucleoid-associated protein (NAP) HU is both highly conserved and ubiquitous. Deletion of HU causes pleiotropic phenotypes, making it difficult to uncover the critical functions of HU within a bacterial cell. In their recent work, Karaboja and Wang (J Bacteriol 204:e00119-22, 2022, ) show that one essential function of Bacillus subtilis HU (HBsu) is to drive the DnaA-dependent initiation of DNA replication at the chromosome origin. We discuss the possible roles of HBsu in replication initiation and other essential cellular functions.
