Purine riboswitches have an essential role in genetic regulation of bacterial metabolism. This family includes the 2′-deoxyguanosine (dG) riboswitch, which is involved in feedback control of ...

The L1 stalk of the large ribosomal subunit undergoes large-scale movements coupled to the translocation of deacylated tRNA during protein synthesis. We use quantitative comparative structural ...

In biological systems, especially for protein molecules, the formation of nanotubular structures is often guided by molecular folding. The folding process organizes interaction sites and enables the ...
