“…By increasingt he relative proportion of MDH, it is possible to enhance the efficiency and the rates of associated cascade reactions, as demonstratedb yF ue tal. [15] To mimic the multienzyme complexes of living cells, enzymesa re often immobilized on carriers.A mong the various approaches (such as using protein [16][17][18][19] and lipid bilayer [20] templates) for the development of artificial enzyme cascade systems, nucleic acids and their nanostructures have recently been applied to achieve particulars patialo rganizationso f enzymes to form metabolons that transfer the substrates between one another.T he common DNA templates used so far are duplex DNA (dsDNA), either in bulk solution [21] or immobilized onto the surfaceo famicroplate [22,23] or an electrode, [24] aptamer-domain-containing DNAs, [25,26] Y-shaped DNA, [27] long DNA chains prepared by the rolling circle amplification (RCA) process, [28] hexagon-like DNA strips, [29] DNA double-crossover (DX) tiles, [15] tuneable DNA tweezers made of DNA DX motifs, [30] three-point star DNA scaffoldsa nd scaffoldedD NA origami [31] with 2D structures, [10,14,[32][33][34] as well as 3D tubes [32,35] and nanocages. [36] Although these DNA-templated enzyme cascade reactions are limited to in vitro studies, they provide ideal systemsf or exploring the chemistry behind cellular enzyme cascade reactions.…”
