    Notizen: The ability of a virus to attach to a suceptible host cell is of utmost importance for the initiation of viral life cycle. Cell surface proteins called viral receptors mediate the initial steps of virus attachment and uptake. Poliovirus (PV) is one of the most studied animal viruses and its interaction with its cellular receptor, the human poliovirus receptor (hPVR) has been well characterized. This review will present our current understanding of the PV/hPVR interaction at the genetic and biochemical level. In addition, we will also discuss the implicatlions of the PV/hPVR interaction on PV tissue tropism and the evolution of the three PV serotypes. Copyright © 1998 John Wiley & Sons, Ltd.

    Beschreibung / Inhaltsverzeichnis: K10[Co4O9], a New Oligooxocobaltate(II)For the first time dark-red single crystals of K10[Co4O9] were obtained by heating mixtures of KO0.48 and CdO (molar ratio 2.7:1) in closed Co-cylinders at 450°C during 73 d.Structure solution and refinement (four-circle diffractometer data, Mo Kα, 2 996 out of 2 996 Io(hkl), R = 5.20%, Rw = 3.03%) confirm the space-group P1 and show structural relationship with Na10[Co4O9] [2]. The lattice constants are a = 667.84(5) pm, b = 917.91(9) pm, c = 908.49(7) pm, α = 119.400(7)°, β = 90.851(7)°, γ = 110.260(6)°, Z = 1. (powder data (Guinier-Simon), standard deviations in parentheses)MAPLE calculations are made and a comparative survey of MAPLE values of oxocobaltates(II) is given.
    Notizen: Erstmals wurde K10[Co4O9] in Form dunkelroter Einkristalle durch „Reaktion mit der Gefäßwand“ beim Tempern inniger Gemenge von KO0,48 mit CdO (molares Verhältnis 2,7:1, 73 d, 450°C) in verschlossenen Co-Bomben dargestellt.Die Strukturaufklärung mittels Vierkreisdiffraktometer (Mo Kα, 2 996 von 2 996 Io(hkl), R = 5,20%, Rw = 3,03%) bestätigt die strukturelle Analogie zu Na10[Co4O9] [2].K10[Co4O9] kristallisiert triklin (Raumgruppe P1) mit a = 667,84(5) pm, b = 917,91(9) pm, c = 908,49(7) pm, α = 119,400(7)°, β = 90,851(7)°, γ = 110,260(6)°, Z = 1.

    Beschreibung / Inhaltsverzeichnis: New Oxides with the “Butterfly-Motive”: Rb6[Fe2O5] and K6[Fe2O5]Rb6[Fe2O5] and K6[Fe2O5] were obtained for the first time by annealing intimate mixtures of “Rb6CdO4” with CdO (molar ratio 1 : 1.1) and KO0.48 with CdO (molar ratio 5.9 : 1) respectively in closed Fe-cylinders. Determination and refinement of the crystalstructure confirms the space group C2/m (four-circle-diffractometer data). Rb6[Fe2O5]: Ag Kα, 720 out of 1220 Io(hkl), R = 9.68%, Rw = 6.09%; a = 718.9pm, b = 1183.1 pm, c = 695.4pm, β = 95.05°, Z = 2; K6[Fe2O5]: MoKα, 1214 Out of 12141o(hkl), R = 3.20070, Rw = 2.48%, a = 691.21 pm, b = 1142.78pm, c = 665.50pm, β = 93.82°, Z = 2. The binuclear unit [O2FeOFeO2]6- already known to be planar with oxoferrates(II) now was observed to be angular here and closely related to Na6[Be2O5].
    Notizen: Rb6[Fe2O5] und K6[Fe2O5] wurden erstmals durch Tempern inniger Gemenge von “Rb6CdO4” mit CdO (im Verhältnis 1 : 1,1) bzw. KO0,48 mit CdO (im Verhältnis 5,9 : 1) in verschlossenen Fe-Zylindern in Form von roten Einkristallen erhalten. Die Strukturaufklärung (Vierkreisdiffraktometerdaten, Rb6[Fe2O5]: Ag Kα, 720 von 1 220 Io(hkl), R = 9,68%, Rw = 6,09%; K6[Fe2O5]: Mo Kα, 1 214 von 1 214 Io(hkl), R = 3,20%, Rw = 2,48%) belegt die Raumgruppe C2/m. Rb6[Fe2O5]: a = 718,9 pm, b = 1183,1 pm, c = 695,4 pm, β = 95,05°, Z = 2. K6[Fe2O5]: a = 691,21 pm, b = 1 142,78 pm, c = 665,50 pm, β = 93,82°, Z = 2. Zum ersten Male wird bei derartigen Ferraten eine deutlich gewinkelte Baueinheit [Fe2O5]6- beobachtet, wie sie analog bei Na6[Be2O5] vorliegt.

MAPLE-values and Charge-distributions are given and discussed.

    First steps from a two-dimensional protein index towards a response-regulation map for Bacillus subtilis (1997)

    Notizen: Data on the identification of proteins of Bacillus subtilis on two-dimensional (2-D) gels as well as their regulation are summarized and the identification of 56 protein spots is included. The pattern of proteins synthesized in Bacillus subtilis during exponential growth, during starvation for glucose or phosphate, or after the imposition of stresses like heat shock, salt- and ethanol stress as well as oxidative stress was analyzed. N-terminal sequencing of protein spots allowed the identification of 93 proteins on 2-D gels, which are required for the synthesis of amino acids and nucleotides, the generation of ATP, for glycolyses, the pentose phosphate cycle, the citric acid cycle as well as for adaptation to a variety of stress conditions. A computer-aided analysis of the 2-D gels was used to monitor the synthesis profile of more than 130 protein spots. Proteins performing housekeeping functions during exponential growth displayed a reduced synthesis rate during stress and starvation, whereas spots induced during stress and starvation were classified as specific stress proteins induced by a single stimulus or a group of related stimuli, or as general stress proteins induced by a variety of entrely different stimuli. The analysis of mutants in global regulators was initiated in order to establish a response regulation map for B. subtilis. These investigations demonstrated that the alternative sigma factor σB is involved in the regulation of almost all of the general stress proteins and that the phoPR two-component system is required for the induction of a large part but not all of the proteins induced by phosphate starvation.
