This paper identifies StIA, a nucleoid-associated protein in Streptococcus pneumoniae that activates DNA topoisomerase I by enhancing its DNA religation step through direct protein-protein interaction.

This study shows RNase R regulates membrane fatty acid composition in Streptococcus pneumoniae by controlling FAS-II gene expression, leading to altered membrane fluidity and sensitivity to detergents.
