Abstract: To enable chromosomal replication, DNA is unwound by the ATPase molecular motor replicative helicase. The bacterial helicase DnaB is a ring‐shaped homo‐hexamer whose conformational dynamics are being studied through its different 3D structural states adopted… read more here.

Abstract: Abstract The replicative DNA helicase translocates on single-stranded DNA to drive replication forks during chromosome replication. In most bacteria the ubiquitous replicative helicase, DnaB, co-evolved with the accessory subunit DciA, but how they function remains… read more here.

DOI: 10.1128/jb.00286-20
Abstract: DnaB is a replicative helicase loader involved in initiating DNA replication in many bacterial species. We investigated the binding preferences of DnaB for its DNA substrate and determined that the C-terminal end of the protein… read more here.
