X-RAY STRUCTURE OF DPS FROM THERMOSYNECHOCOCCUS ELONGATUS
Overview
DNA-binding proteins from starved cells (Dps proteins) protect bacteria, primarily from oxidative damage. They are composed of 12 identical, subunits assembled with 23-symmetry to form a compact cage-like structure, known to be stable at temperatures > 70 degrees C and over a wide pH, range. Thermosynechococcus elongatus Dps thermostability is increased, dramatically relative to mesophilic Dps proteins. Hydrophobic interactions, at the dimeric and trimeric interfaces called Dps-like are replaced by, salt bridges and hydrogen bonds, a common strategy in thermophiles., Moreover, the buried surface area at the least-extended Dps-like interface, is significantly increased. A peculiarity of T. elongatus Dps is the, presence of a chloride ion coordinated with threefold symmetry-related, ... [(full description)]
