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

A kinetic study of DNA-based catalyticenantioselective Friedel–Crafts alkylation and Michael additionreactions showed that DNA affects the rate of these reactions significantly. Whereas in the presence of DNA, a large acceleration was found for the Friedel–Crafts alkylation and a modest acceleration in the Michael addition of dimethyl malonate, a deceleration was observed when using nitromethane
