WebA plot of backbone S2 versus crystallographic B factors is presented in Fig. I C. An inverse correlation would intuitively be expected si nce high mobility in solution as evidenced by a low 5 2 would manifest itself by random thermal motions or static conformational disorder in the crystal lattice, re sulting in large B fa ctors. WebThe meaning of CRYSTALLOGRAPHIC is of or relating to crystals or crystallography. Recent Examples on the Web The Dark Lady of DNA, which probably did more than …

WebCrystallographic B-factors are affected by packing and other special features of the crystalline state [10]. In addition, many factors may reduce the intensities of the “reflections” in a protein crystal’s X-ray diffraction pattern, and hence under aCC-BY-ND 4.0 ... WebBDB: databank of PDB files with consistent B-factors Protein structures available from the PDB contain for each atom the coordinates, the occupancy and the B-factor that indicates the mobility of the atom. The values that should represent B-factors can relate to atomic motions in different ways. ipers investments
vGNM: a better model for understanding the dynamics of
WebMay 30, 2024 · A clear correlation between motions on a picosecond-to-nanosecond time scale determined from NMR spectroscopy and crystallographic B factors has been established . Qualitatively, the quenching of fast time scale motions in AdK following binding to Ap5a is reinforced by analysis of crystallographic B factors in apo wild-type AdK … WebMay 1, 2024 · Observed crystallographic B-factor values correspond to the leftmost 10% of the σ-range depicted in Fig. 4. In this respect, it should be kept in mind that internal motion in crystal structures is in general reduced by conducting diffraction measurements at low temperatures [23] and possible restrictions imposed by crystal packing. WebJun 8, 2007 · In recent years, the simple coarse-grained Gaussian Network Model (GNM) has been fairly successful in interpreting crystallographic B-factors. However, the model clearly ignores the contribution of the rigid body motions and the effect of crystal packing. ipers iowa percentage
