Electrochemical control of quantum interference in anthraquinone-based molecular switches [PDF]
, 2010 Using first-principles calculations we analyze the electronic transport properties of a recently proposed anthraquinone based electrochemical switch. Robust conductance on/off ratios of several orders of magnitude are observed due to destructive quantum ...

A Novel Molecular Switch [PDF]
Journal of Molecular Biology, 2009 Transcriptional regulation is a fundamental process for regulating the flux of all metabolic pathways. For the last several decades, the lac operon has served as a valuable model for studying transcription. More recently, the switch that controls the operon has also been successfully adapted to function in mammalian cells.

Nucleic acid molecular switches
Trends in Biotechnology, 1999 Natural and artificial ribozymes can catalyse a diverse range of chemical reactions. Through recent efforts in enzyme engineering, it has become possible to tailor the activity of ribozymes to respond allosterically to specific effector compounds. These allosteric ribozymes function as effector-dependent molecular switches that could find application ...
