Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and ...

Deep in our cells, a wide range of processes are occurring constantly. These cellular processes rely on enzymes to act as catalysts and set off a series of molecular interactions. There are still many ...

The very cells that created us may have a role in saving our lives. Scientists have always been amazed by the energy production system in a sperm’s tail. The system drives flagellar movement and is ...

A UCSF team finds a liver protein, released with exercise, that improves memory in aging and Alzheimer’s disease by repairing ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

After a long search, RIKEN researchers have identified an enzyme crucial for keeping lipid-linked sugar chains in check in yeast cells. This finding, published in the Journal of Cell Biology, reveals ...

A protein reinforces the blood–brain barrier, which becomes leaky with age. Exercise prevents brain ageing and memory loss by strengthening the blood–brain barrier, the structure that keeps harmful ...

A new study shows exercise releases a liver enzyme that repairs aging brain blood vessels and restores memory in mice.

Nicotiana benthamiana plants in a lab at UC Davis. Plants form new branches when a hormone called strigolactone breaks down. UC Davis plant biologists have now defined the enzymes that break down ...

Scientists uncover a pivotal enzyme, XccOpgD, and its critical role in synthesizing C G16, a key compound used by Xanthomonas pathogens to enhance their virulence against plants. This breakthrough ...
