On the basis of biochemical, in vivo and X-ray structural analyses, we now report that HutP uses its dual RNA-binding surfaces to access two XAGrich regions (sites I and II) within the terminator RNA to ...
In this process, HutP initiates destabilization at the 5'-end of its mRNA by binding to the first XAG-rich region (site I) and then accesses the second XAG-rich region (site II), located downstream of ...
