Research Highlights
Dr Daniel Martin working in the Matyushov group has recently took advantage of one of the fastest high performance supercomputers (Anton, D. E. Shaw) to look at electron tunneling in proteins. Membrane-bound bc1 complex is one of the key elements of biology’s energy production chain in mitochondria of animals and photosynthetic centers of bacteria. Longer than 10 microseconds of fully atomistic computer simulations have allowed for the first time to study the protein's low frequency motions driving electron transfer. A broad range of fluctuations, spanning from picoseconds to microseconds, affects the transition. Surprisingly, slow motions, in the range 0.1-1.6 microseconds turned out to be particularly important. This work recently appeared in the J. Chem. Phys. 142, 161101 (2015).
