-------------------------------------------------------------------- COLLOQUIUM OF THE COMPUTATIONAL MATERIALS SCIENCE CENTER School of Computational Sciences (CSI 898-Sec 001) -------------------------------------------------------------------- Computational Studies of Iron-sulfur Proteins: Electronic Devices of Living Cells Toshiko Ichiye Chemistry Department, Georgetown University, Washington D.C. Iron-sulfur proteins serve as electronic devices that control energy flow in living cells. Here, the underlying molecular mechanisms are shown that allow [4Fe-4S] ferredoxins to act as efficient wires for moving electrons. In addition, mutations are identified in these ferredoxins that can provide a driving force for the electron flow. Finally, a mechanism is presented for the fission of the [4Fe-4S] cluster, which may play a role in the regulation of activity of certain [4Fe-4S] proteins. September 11, 4:30 pm Room 301, Research I, Fairfax Campus Refreshments will be served at 4:15 PM. ---------------------------------------------------------------------- Find the schedule at http://www.cmasc.gmu.edu/seminar/schedule.html --------------------------------------------------------------------
