abstract：:Ribosomes are translational machineries that catalyse protein synthesis. Ribosome structures from various species are known at the atomic level, but obtaining the structure of the human ribosome has remained a challenge; efforts to address this would be highly relevant with regard to human diseases. Here we report the...
