The structures of ribosomal complexes represent a triumph of structural biology. Yet these structures lack a time axis: dynamic measurements are needed to understand the mysteries of translation. Here we present our broad efforts to develop and use single‐molecule fluorescence methods to track translation in real time. Using fluorescent labels on transfer RNAs, factors, mRNAs and ribosomal subunits, we have mapped conformational and compositional dynamics of the translational machinery during protein synthesis. Our focus has recently been on the dynamics of initiation, by which translational reading frame is established.Read More
