Crystal structure of PKG I suggests a new activation mechanism

Protein kinases, most scientists would agree, regulate nearly every aspect of cell life. It is no surprise, then, that having faulty protein kinases may lead to a number of human conditions, including cardiovascular diseases, ...

Outsourcing crystal growth... to space

Sometimes, distance can lend a new perspective to a problem. For Japanese researchers studying protein crystal growth, that distance was 250 miles up—the altitude at which the International Space Station (ISS) orbits the ...

Digital enhancement of cryoEM photographs of protein nanocrystals

When cryoEM images are obtained from protein nanocrystals the images themselves can appear to be devoid of any contrast. A group of scientists from the Netherlands have now demonstrated that lattice information can be revealed ...

Bacteriorhodopsin crystals consume their smaller counterparts

A group of biophysicists from Moscow Institute of Physics and Technology (MIPT) and their international colleagues have studied the crystallization of molecules of the membrane protein bacteriorhodopsin. They have demonstrated ...

Scientists unravel elusive structure of HIV protein

HIV, or human immunodeficiency virus, is the retrovirus that leads to acquired immunodeficiency syndrome or AIDS. Globally, about 35 million people are living with HIV, which constantly adapts and mutates creating challenges ...

How frogs and fish can help us learn to freeze humans

From Star Wars to Futurama to Alien, the idea that humans can be frozen in time in order to be awoken later is a well-established sci-fi trope. While stopping biological time or inducing long-term hibernation is still as ...
