Detection of transcription factor binding sites using Rényi entropy
(IEEE Press. Institute of Electrical and Electronics Engineers, 2008)
Text en actes de congrés
Accés obertDuring the process of protein synthesis, transcription of DNA to messenger RNA starts with the binding of the transcription factors to the promoter. One of the issues on the prediction of transcription factor binding is ... -
DNA-catalyzed Henry reaction in pure water and the striking influence of organic buffer systems
(2015-03-04)
Article
Accés obertIn this manuscript we report a critical evaluation of the ability of natural DNA to mediate the nitroaldol (Henry) reaction at physiological temperature in pure water. Under these conditions, no background reaction took ... -
