    Notes: The lysC/asd gene cluster of Corynebacterium glutamicum ATCC 13032 was cloned and sequenced. The lysC locus coding for aspartokinase consists of two in-frame overlapping genes, lysCα encoding a protein of 421 amino acids (Mr 44300) and lysCβ encoding a protein of 172 amino acids (Mr 18600). The C. glutamicum aspartokinase was purified and found to contain two proteins of Mr 47000 and Mr 18000.A C. glutamicum mutant expressing a feedback-resistant aspartokinase was shown to be changed in a single base pair of the lysCβ gene, leading to an amino acid exchange in the β-subunit of the aspartokinase. In addition, the identified mutation was found to be responsible for the enhanced expression of the asd gene located downstream of lysC.

    Notes: Summary Wilson disease (WD) is an autosomal recessive disorder of copper metabolism. A minimum recombinant analysis using D13S22, ESD, RB1, D13S31, D13S55, D13S26, D13S39, and D13S12, all localized at 13q14-q22, has been carried out in 20WD families of Northwest-European origin. No inconsistencies have been observed with respect to locus order or location of the WD locus (WND) compared with previous linkage studies. D13S31 was mapped as the closest marker proximal to WND, whereas D13S55 and D13S26 were mapped as the closest markers distal to WND. We have identified a crossover between WND and D13S31 in one family and a crossover between WND and D13S55 in another. These crossover sites can be used as reference points for new chromosome 13q14-q21 markers, and are therefore important for a more accurate mapping of the WD locus.

    Description / Table of Contents: Single Crystal Investigation on AgF2For the first time single crystals of AgF2 (black, metalic bright) have been obtained by heating AgF2 powder under a mixture of HF and F2 in autoclaves at 400°C. It crystallizes orthorhombic in the space group Pbca - D2h15 (Nr. 61) - with a = 556.8(1), b = 583.1(1) and c = 510.1(1) pm; Z = 4.The Madelung Part of Lattice Energy, MAPLE, and the Effective Coordination Number, ECoN, via the Mean Fictive Ionic Radii, MEFIR, are calculated and discussed.
    Notes: Erstmals wurden schwarze, metallisch glänzende Einkristalle von AgF2 durch Erhitzen des mikrokristallinen AgF2 dargestellt (Monel-Autoklaven, T ≈ 400°C, HF/F2-Gemisch, 4 d). Die röntgenographische Untersuchung (a = 556,8(1); = 583,1(1); c = 510,1(1) pm; Z = 4; Parameter siehe Text) bestätigt die aus Neutronenbeugungsuntersuchung ermittelte Raumgruppe Pbca - D2h15 (Nr. 61) und ergibt Lageparameter, die mit den damals ermittelten Werten praktisch übereinstimmen. Der Madelunganteil der Gitterenergie, MAPLE, sowie Effektive Koordinationszahlen, ECoN, werden über Mittlere Fiktive Ionenradien, MEFIR, berechnet und diskutiert.
