Metal ion-induced folding of the DUF-3268 k-junction analyzed by FRET. A construct analogous to that shown schematically in Figure 2A based on the DUF-3268 k-junction was used in these experiments. (A) Titration of the DUF-3268 k-junction with Mg2+ ions. Filled circles: natural sequence DUF-3268 k-junction. Open circles: DUF-3268 k-junction with L1H substitution. (B) Titration of the DUF-3268 k-junction with Na+ ions.
