Structural and functional studies of a potassium ion channel that is opened and closed by different ligands have revealed a novel gating mechanism.

Cauliflower mosaic virus reacts immediately when aphids feed on the host plant, and this boosts its chances of being taken up and transmitted by the insects to a new plant.

A sudden fall in the levels of the coenzyme NADPH within cells could have a central role in the process of aging.

The structure of a large hydrogenase complex involved in the production of methane by microbes has been determined with cryo-electron microscopy.

A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.

A modified form of Green Fluorescent Protein integrated into an ammonium transporter provides a sensor that can be used to monitor transport activity in vivo.

The basal body of the type-III secretion system of Yersinia enterocolitica within bacterial membranes shows elasticity and is longer than related isolated systems.

Structural studies reveal the mechanism by which a HECT E3 ubiquitin ligase carries out E2-to-E3-to-substrate ubiquitin transfer and prioritizes target lysines for ubiquitination.

Potassium ions enter and leave human sperm cells via a calcium-dependent ion channel that is also pH-independent.

Genes located within cellular organelles impact phenotype more than expected due to their interactions with nuclear genes.
