While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...

Enzymes help with specific functions that are vital to the operation and overall health of the human body. They help speed up chemical reactions and are essential for respiration, digestion, muscle ...

Most drugs operate via the membranes that surround the body's cells. A study by researchers at Karolinska Institutet in Sweden has now mapped the structure and mechanism of MGST2, a membrane enzyme ...

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, ...

Cancer cells have an insatiable appetite for energy as they multiply more rapidly than normal cells. Greedy cancer cells hijack various cellular functions to find and exploit energy and other ...

Malathy Palayam, Aleczander Young, Lior Tal, and Nitzan Shabek at the UC Davis Department of Plant Biology are exploring the mechanism by which the plant hormone strigoractone regulates a massive ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that ...

Scientists used x-rays to decipher the three-dimensional structure of the main protease of the virus that causes COVID-19 at different temperatures. The background image shows the full structure at ...

As sessile organisms, plants have to continually adapt their growth and architecture to the ever-changing environment. To do so, plants have evolved distinct molecular mechanisms to sense and respond ...
