DNA-Functionalized, Bivalent Proteins

Bivalent DNA conjugates of β-galactosidase (βGal), having pairs of oligonucleotides positioned closely on opposing faces of the protein, have been synthesized and characterized. These structures, due to their directional bonding characteristics, allow for the programmable access of one-dimensional protein materials. When conjugates functionalized with complementary oligonucleotides are combined under conditions that support DNA hybridization,...
