    Description / Table of Contents: Crystal Structure Investigations of Tl2AgI3 und NaAgI2 · 3 H2OTl2AgI3 was synthesized by the reaction of TlI with AgI in aqueous HI (25%) in a pressure vessel. The compound crystallizes in the rhombohedral space group R3; a = 1044,3(2); c = 1993,5(3)pm; Z = 9. The crystal structure contains trinuclear anions [Ag3I8]5- and [ITl6]5+ octahedra. The anions are composed of two AgI4-tetrahedra which are connected to an AgI6 octahedron via common faces.Single crystals of NaAgI2 · 3 H2O were formed by reaction of NaI with AgI in aqueous solution. The compound crystallizes in the orthorhombic space group Pbca with lattice parameters a = 711,2(2); b = 939,8(3); c = 2462,2(4) pm; Z = 8. The crystal structure is built up by polymeric layers ∞2[AgI3/3I½1/2-] of corner sharing AgI4 tetrahedra (GaOCl type) and ∞1[Na(H2O)4/2(H2O)I½1/2+] octahedra chains.
    Notes: Tl2AgI3 wurde durch Umsetzung von TlI mit AgI in wäßriger HI (25%) in einem Aufschlußautoklaven kristallin erhalten. Es kristallisiert in der rhomboedrischen Raumgruppe R3; a = 1044,3(2); c = 1993,5(3) pm; Z = 9. Die Kristallstruktur ist aus dreikernigen Anionen [Ag3I8]5- und [ITl6]5+-Oktaedern aufgebaut. Die Anionen bestehen aus zwei AgI4-Tetraedern, die über gemeinsame Flächen an ein AgI6-Oktaeder gebunden sind.Die Verbindung NaAgI2 · 3 H2O wurde aus wäßriger Lösung durch Umsetzung von NaI mit AgI einkristallin gewonnen. Die orthorhombische Raumgruppe Pbca hat die Zellparameter a = 711,2(2); b = 939,8(3); c = 2462,2(4) pm; Z = 8. Die Kristallstruktur ist durch polymere Schichten ∞2[AgI3/3I½1/2-] aus eckenverknüpften AgI4-Tetraedern (GaOCl-Typ) und ∞1[Na(H2O)4/2(H2O)I1/2+]-Oktaederketten gekennzeichnet.

    Notes: Amine oxidase from the yeast Hansenula polymorpha is a peroxisomal protein. The signal for routing of the protein into peroxisomes has not been identified yet. Expression of a mutant amine oxidase in H. Polymorpha has revealed that the C-terminal sequence, which possesses an internal SRL tripeptide, is not involved in targeting (Faber et al., unpublished). We have explored heterologous expression of the amine oxidase gene (AMO) in Saccharomyces cerevisiae to investigate the conservation of peroxisomal targeting pathways between yeasts. Surprisingly, wide-type amine oxidase is not recognized as a peroxisomal protein by S. cerevisiae. The enzyme, which was fully active and acumulated to levels similar to those found in H. polymorpha, stayed entirely in the cytosol. However, fusing a SKL or a SRL sequence to the C-terminus forced the protein at least partially into peroxisomes of the heterologous host. These data suggest that the functional targeting sequence of amine oxidase may differ from the C-terminal peroxisomal targeting signal S/C/A-K/R/H-L (Gould et al., 1989). Contrary to the established tripeptide motif, the amine oxidase targeting signal appears not to be conserved between the different yeast species.
