A new pick‐up line : The first uranyl‐selective DNA‐binding protein is designed using the E. coli nickel(II)‐responsive protein NikR as the template. The resulting NikR′ protein binds uranyl (see picture) with a dissociation constant K d =53 n M and selectively binds to DNA in the presence of uranyl.
