In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps toward folding proteins into their correct three-dimensional structures ...

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 ...
