An uncommon [K(+)(Mg(2+))(2)] metal ion triad imparts stability and selectivity to the Guanidine-I riboswitch
The widespread ykkC-I riboswitch class exemplifies divergent riboswitch evolution. To analyze how natural selection has diversified its versatile RNA fold, we determined the X-ray crystal structure of the Burkholderia sp. TJI49 ykkC-I subtype-1 (Guanidine-I) riboswitch aptamer domain. Differing from...
