The paper identifies and characterizes a cryptic START domain in HD-ZIPIII transcription factors, showing its role in subcellular localization, DNA binding, and ligand recognition.

The paper reconstructs the ancestral complexity of bacterial flagellar systems, identifying 28 additional conserved gene families, suggesting the last bacterial common ancestor had a complex flagellum with more components than extant bacteria.

This study identifies FliO as a nearly ubiquitous and ancestral core component of the bacterial flagellar type III secretion system, showing structural diversity and functional repurposing across bacterial species.

The paper identifies a mechanism by which paralogous HD-ZIPIII transcription factors generate distinct regulons through differential usage of shared binding sites, mediated by their START domains.

The paper identifies FlhE as a periplasmic chaperone that prevents the formation of periplasmic flagella in Salmonella, which disrupts cell wall synthesis and causes cell lysis.

This paper identifies two disulfide-reducing pathways required for cytochrome f maturation in Chlamydomonas reinhardtii, with CCS4 playing a dual role in stabilizing CCDA and participating in a CCS5-independent pathway.
