... FEBS monomers are involved in RNA binding, and disrup- tion of the orientation of the amino terminal hairpin by the C-terminal tail of the antitoxin inactivates the toxicity of the protein. The crystal ... that RNA binding to one of the symmetric binding surfaces introduces structural changes in the Kid protein that prevent the binding of a second substrate to the second sym...
