New insights to the function of molecular chaperones

(Phys.org)—Heidelberg molecular biologists have gained new insights into the function of so-called molecular chaperones in protein synthesis. The team headed by Dr. Günter Kramer and Prof. Dr. Bernd Bukau of the DKFZ-ZMBH ...

Simplifying genetic codes to look back in time

(Phys.org)— Daisuke Kiga and co-workers at the Department of Computational Intelligence and Systems Science at Tokyo Institute of Technology, together with researchers across Japan, have shown that simpler versions of the ...

Researchers piece together how proteins fold

(Phys.org) -- A new method for looking at how proteins fold inside mammal cells could one day lead to better flu vaccines, among other practical applications, say Cornell researchers.

Study of ribosome evolution challenges 'RNA World' hypothesis

In the beginning – of the ribosome, the cell's protein-building workbench – there were ribonucleic acids, the molecules we call RNA that today perform a host of vital functions in cells. And according to a new analysis, ...

X-rays reveal why sea urchins are no easy prey

(PhysOrg.com) -- The spine of a sea urchin is 99.9% chalk, a very common material forming tiny crystals that are very hard but easy to break apart. Scientists have now discovered how these marine animals use chalk or lime ...

Researchers uncover new function for cell master regulator

(PhysOrg.com) -- TORC1 is a master regulator in cells, playing a key role in such diverse processes as gene expression and protein synthesis. While previous studies have described the role that TORC1 plays in these processes, ...

Shedding light on a photosensitive protein

Even without eyes, many single-celled organisms can perceive and react to light. This is achieved via rhodopsins, proteins at the cell surface that trigger responses to specific wavelengths of light by directing the flow ...
