A series of structures of the eukaryotic protein-synthesis machinery are imaged at high resolution in defined states of the elongation phase of protein synthesis. Analysis suggests that there are ...

Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded ...

Scientists at the University of Manchester have identified an extra step in protein production, a major activity of all cells, which they believe impacts particularly on how our cells respond to ...

Scientists have unraveled the step-by-step activation process of a protein with a deep evolutionary history in all domains of life, opening the door to harnessing its functions for use as a ...

Cryo-EM structure of the Giardia ribosome reveals a highly compact, GC-rich rRNA with eukaryotic r-proteins. (A) Structure of the Giardia ribosome with all the r-proteins colored (SSU, shades of blue ...

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the ...
