SARS-CoV-2: Over 700 million infected, nearly 7 million dead, but vaccines mitigate and contain the pandemic.

It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes – the biological ca ...

Proteins are the "workhorses" in every living cell and constitute the chemical basis of life. These little machines are required to turn food into energy, to manage motion and brain activities and to fight off bacteria and viruses.

Researchers recently discovered a completely novel group of proteins that functions as a switch to regulate biological activity. Now they have analyzed all known protein structures and it turns out that this group exists in all domains of life, in viruses and bacteria as well as in fungi, plants and animals, including humans.

Scientists discover fundamental regulation mechanism of proteins Proteins perform a vast array of functions in the cell of every living organism with critical roles in almost every biological process. Not only do they run our metabolism, manage cellular signaling and are in charge of energy production, as antibodies they are also the frontline workers of our immune system fighting human pathogens like the coronavirus. In view of these important duties, it is not surprising that the activity of proteins is tightly controlled. There are numerous chemical switches that control the structure and,...
