Traceless and multifunctional linkers for the generation of small molecules on solid supports.

abstract：:Protein synthesis is inherently a dynamic process, requiring both small-scale and large-scale movements of tRNA and mRNA. It has long been suspected that these movements might be coupled to conformational changes in the ribosome, and in its RNA moieties in particular. Recently, the nature of ribosome structural dynami...
