The paper investigates the structural interaction of the toxin EatA with its partner proteins TapA1 and TapA2, and predicts its interaction with EsxT-EsxU using mutagenesis and bacterial 2-hybrid assays.

The paper identifies a type VII-secreted toxin in mycobacteria that enables inter-bacterial competition by targeting arabinogalactan.

This study identifies TslM as a novel reverse domain arrangement substrate of the Staphylococcus aureus type VII secretion system, revealing its lipase activity and secretion mechanism.

The paper identifies two distinct immunity protein families that neutralize a bacterial toxin from different compartments.

The paper identifies and characterizes anhydro-sialic acid transporters in bacteria, showing their specific or promiscuous substrate preferences.

The paper identifies novel tail-anchored Tat substrates in bacterial genomes through bioinformatics and experimental validation, revealing new iron-sulphur proteins and candidate substrates without cofactors.

This study identifies eight new subtypes of the type VII secretion system in Gram-positive bacteria, revealing unexpected diversity in their composition and potential functions.
