Mirror mirror on the wall: By taking advantage of the unique structural features of L‐DNA, the first examples of left‐helical enantioselective induction in the field of DNA‐based asymmetriccatalysis were realized. Most importantly, this approach is the only one that allows a reliable and predictable access to both enantiomers for any given reaction.
We report here the first example of an RNA-based catalyst involving a catalytically active metal complex interacting in a non-covalent fashion with short RNA sequences.

construct artificial metalloenzymes (ArMs) for enantioselective catalysis. DNA-based ArMs containing duplex and G-quadruplex scaffolds have been widely investigated, yet RNA-based ArMs are scarce. Here we report that a cyclic dinucleotide of c-di-AMP and Cu2+ ions assemble into an artificialmetalloribozyme (c-di-AMP⋅Cu2+ ) that enables catalysis of enantioselective Friedel-Crafts reactions in aqueous

A human telomeric G-quadruplex (G4DNA) metalloenzyme, assembled with G4DNA and Cu2+ ions, can catalyze the enantioselective FriedelâCrafts (FâC) reaction in water with good enantioselectivity (up to 75% ee). Furthermore, we found that the absolute configuration and the enantioselectivity of the product largely depend on the conformation and the sequence of G4DNA.

to a protein scaffold is an attractive approach to the construction of artificialmetalloenzymes since this is conveniently achieved by self-assembly. Here, we report a novel design for supramolecular artificialmetalloenzymes that exploits the promiscuity of the central hydrophobic cavity of the transcription factor Lactococcal multidrug resistance Regulator (LmrR) as a generic binding site for planar
