This study investigates the architecture of the T7 leading-strand replisome to determine whether DNA unwinding is driven by helicase or polymerase, concluding support for the helicase-driven unwinding model.

The paper presents high-resolution structures of Helicobacter pylori TlpD, revealing how ligand-binding perturbations propagate through coiled-coils to regulate kinase interfaces.

This study identifies YlaN as an Fe(II) binding protein in S. aureus that relieves Fur-mediated repression of gene expression during Fe deprivation.
