The Molecular Origin of Like-Charge Arginine-Arginine Pairing in Water Jií Vondrek, Philip E. Mason, Jan Heyda, Kim D. Collins and Pavel Jungwirth J. Phys. Chem. B, 2009, 113 (27), pp 9041–9045 ================================================== From: W H <[email protected]> Hi Phoebe, I encountered a similar situation during my thesis work. Maybe these references can help: Magalhaes, A., B. Maigret, et al. (1994). "Contribution of Unusual Arginine-Arginine Short-Range Interactions to Stabilization and Recognition in Proteins." J. Protein Chem. 13(2): 195-215. Soetens, J. C., C. Millot, et al. (1997). "Effect of polarizability on the potential of mean force of two cations. The guanidinium-guanidinium ion pair in water." J.
