Abstract
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 nM and selectively binds to DNA in the presence of uranyl.
