We know of several studies on WATER residence times near both proteins and DNA (Wuttrich, Otting, Gueron, etc.) Is there any comparable research on ION experimental or theoretical residence times for Na+, Cl- or other monovalent ions which are coordinated with either proteins or DNA? Thanks, Linjing Yang yanglj ":at:" biomath.nyu.edu
