Deep-sea osmolyte makes biomolecular machines heat-tolerant

Researchers have discovered a method to control biomolecular machines over a wide temperature range using deep-sea osmolyte trimethylamine N-oxide (TMAO). This finding could open a new dimension in the application of artificial ...

The plus and minus of microtubules

Microtubules are protein polymers that assemble into dynamic structures, essential for cell division, shape, motility, and transport of intracellular cargos.

Motor proteins and membrane dynamics

Membranes composed of a lipid bilayer define the outer surface of nucleated cells (the plasma membrane) and delimit the vital organelles within these cells, such as mitochondria and nuclei. The membrane curvature determines ...

Study uncovers key step in cell protein production

Scientists at the University of Sheffield have discovered how genes create proteins in research which could aid the development of treatments for human diseases.

Keeping our cells stable: A closer look at microtubules

Microtubules help to regulate cell structure. A group of Japanese researchers have used cryo-electron microscopy to shed light on how a certain protein keeps microtubules stable and regulates microtubule-based transport within ...

Pile-ups in protein transport

Anyone who has ever tried to find a way through a crowded pedestrian zone has—literally—run into the problem: While some people choose to weave their way through the gaps, others stick to the straight and narrow, and ...

Motor protein

Motor proteins are a class of molecular motors that are able to move along the surface of a suitable substrate. They are powered by the hydrolysis of ATP and convert chemical energy into mechanical work.
