Computational protein design.

abstract：:Quantitative microscopy is needed to understand reactions or phenomena carried out by biological molecules such as enzymes, receptors, and membrane-localized proteins. Counting the biomolecules of interest in single organelles or cellular compartments is critical in these approaches. In this brief perspective, we focu...

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...
