On the nature of a glassy state of matter in a hydrated protein: Relation to protein function.
M.M.Teeter, A.Yamano, B.Stec, U.Mohanty.
Diverse biochemical and biophysical experiments indicate that all proteins, regardless of size or origin, undergo a dynamic transition near 200 K. The cause of this shift in dynamic behavior, termed a "glass transition," and its relation to protein function are important open questions. One explanation postulated for the transition is solidification of correlated motions in proteins below the transition. We verified this conjecture by showing that crambin's radius of gyration (Rg) remains constant below approximately 180 K. We show that both atom position and dynamics of protein and solvent are physically coupled, leading to a novel cooperative state. This glassy state is identified by negative slopes of the Debye-Waller (B) factor vs. temperature. It is composed of multisubstate side chains and solvent. Based on generalization of Adam-Gibbs' notion of a cooperatively rearranging region and decrease of the total entropy with temperature, we calculate the slope of the Debye-Waller factor. The results are in accord with experiment.

Figure 1.
Fig. 1. A and B substates of the Asn-12 side chain in crambin coupled to the A and B water networks at 130 K. Note that the electron density for the water A and B substates are well separated for W105 and W119. Hydrogen bonds drawn as dotted lines are all between 2.75 and 3.11 Å. Electron density (2F[o] F[c]) is contoured at the 2 level.
Figure 2.
Fig. 2. Water rings in crambin at 160 K. (a) A stereodiagram of the extensive network of water rings from the largest crystal solvent region. Single letter codes (T = Thr, P = Pro, D = Asp) are used for the protein and symmetry-related molecules (residues with # after their number.) Electron density (2F[o] F[c]) is contoured at the 1.5 level. Water-water hydrogen bonds, as well as protein bonds, are shown in thick lines. One pentagon ring at the left (114BO-116BO-142O-165O-99O) is repeated at the right for 2-fold-screw-axis related waters (#). Water molecules with B in their label indicate that the ring arrays shown here are for the B substate and have partial occupancy. This cluster of rings contains two pentagon rings, three hexagon rings, and one heptagon ring. Hexagons can adopt a chair conformation when two waters in the ring hydrogen bond to the same carbonyl (97O# and 150#). Electron density (2F[o] F[c]) is contoured at the 1.5 level. (b) Number of rings vs. temperature for crambin water molecules in the largest water region. The number of rings is plotted for 130 K, 160 K, 200 K, 220 K, and 293 K. Pentagons are represented by filled triangles, hexagons by shaded squares, and heptagons by open circles. At 293 K, the remaining pentagons cluster near Leu-18 (37). Note that data for 160 K, 200 K, 220 K, and 240 K are on the same crystal.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
