AI Summary (NQ-processed)
A joint research team from the University of Tokyo, Tokyo University of Science, Okayama University, and the Japan Science and Technology Agency (JST) has elucidated the molecular mechanism by which the protein YheS restarts translation by extracting tRNA from stalled ribosomes. Using cryo-electron microscopy, they determined the 3D structure of the complex formed between YheS and ribosomes arrested during SecM synthesis. This discovery deepens understanding of a fundamental life process and holds promise for precise control of protein expression and optimized production of useful proteins in biomanufacturing.
