Uncovering a mechanism for how inflammatory signaling is opposed by a phosphatase identifies a potential druggable target to treat E. coli sepsis.

Applying ancestral sequence reconstruction techniques to protein kinases reveals the mutations that underlie different modes of activation.

The role of an amino acid-dependent tRNA modification as a nutrient sensor and regulator of metabolic homeostasis has been discovered.

The identification of ACNQ as an extracellular electron shuttle solves a longstanding problem in bacterial physiology and provides new tool for bioenergy development.

Shewanella oneidensis bacteria use an abiotic reaction to help shuttle electrons outside of the cell.

The combination of in vitro investigations, the zebrafish screening model and rodent experiments offered a unique approach to optimizing nanoparticles modified with Hepatitis B virus-derived peptides to specifically target hepatocytes.

The AAA+ protein unfolding motor ClpX grips substrates with the uppermost part of its substrate-binding pore, and requires interactions with hydrophobic amino acid side chains to operate with optimal efficiency.

An alternative iron storage system based on a 9.6 megadalton microbial protein compartment is able to sequester and store large amounts of iron.

ESCRT-III heteropolymers utilize non-specific lateral electrostatic interactions to recognize one another, which may enable the polymers to slide along one another and adapt to different curvatures.

Detection of unbinding transitional states in the charybdotoxin first-order dissociation from a Kv-channel reveals that the bound neurotoxin wobbles, suggesting diverse intermediates and dissociation pathways in this protein–protein interaction.
