      Charge transfer in dynamical biosystems, or the treachery of (static) images 

      Beratan, David N.; Liu, C.; Migliore, A.; Polizzi, N. F.; Skourtis, Spiros S.; Zhang, P.; Zhang, Y. (2015)
      ConspectusThe image is not the thing. Just as a pipe rendered in an oil painting cannot be smoked, quantum mechanical coupling pathways rendered on LCDs do not convey electrons. The aim of this Account is to examine some ...

      Composition and histone substrates of polycomb repressive group complexes change during cellular differentiation 

      Kuzmichev, A.; Margueron, R.; Vaquero, A.; Preissner, T. S.; Scher, M.; Kirmizis, Antonis; Ouyang, X.; Brockdorff, N.; Abate-Shen, C.; Farnham, P.; Reinberg, D. (2005)
      Changes in the substrate specificities of factors that irreversibly modify the histone components of chromatin are expected to have a profound effect on gene expression through epigenetics. Ezh2 is a histone-lysine ...

      Silencing of human polycomb target genes is associated with methylation of histone H3 Lys 27 

      Kirmizis, Antonis; Bartley, S. M.; Kuzmichev, A.; Margueron, R.; Reinberg, D.; Green, R.; Farnham, P. J. (2004)
      Polycomb group (PcG) complexes 2 and 3 are involved in transcriptional silencing. These complexes contain a histone lysine methyltransferase (HKMT) activity that targets different lysine residues on histones H1 or H3 in ...

      Steering electrons on moving pathways. 

      Beratan, David N.; Skourtis, Spiros S.; Balabin, I. A.; Balaeff, A.; Keinan, S.; Venkatramani, R.; Xiao, D. (2009)
      Electron transfer (ET) reactions provide a nexus among chemistry, biochemistry, and physics. These reactions underpin the "power plants" and "power grids" of bioenergetics, and they challenge us to understand how evolution ...
