Genome regulation relies on complex and dynamic interactions between DNA proteins. Recently, powerful methods have emerged that leverage third-generation sequencing to map protein-DNA genome-wide. For example, Directed Methylation with Long-read (DiMeLo-seq) enables mapping of along long, single chromatin fibers, including in highly repetitive genomic regions. However, DiMeLo-seq involves lossy centrifugation-based wash steps limit its applicability many sample types. To address this, we...
In enterobacteria such as Escherichia coli, the general stress response is mediated by σs, stationary phase dissociable promoter specificity subunit of RNA polymerase. σs degraded ClpXP during active growth in a process dependent on RssB adaptor, which thought to be stimulated phosphorylation conserved aspartate its N-terminal receiver domain. Here we present crystal structure full-length bound beryllofluoride phosphomimic. Compared IraD anti-adaptor, our new with reveals conformational...
In the model organism Escherichia coli and related species, general stress response relies on tight regulation of intracellular levels promoter specificity subunit RpoS. RpoS turnover is exclusively dependent RssB, a two-domain regulator that functions as an adaptor delivers to ClpXP for proteolysis. Here, we report crystal structures receiver domain RssB both in its unphosphorylated form bound phosphomimic BeF3 - . Surprisingly, find only modest differences between these two structures,...
