    Notes: Abstract  The cDNA clone pSM/1.6 encoding the 26.5-kDa precursor molecule of the 16/17-kDa microneme antigen of Sarcocystis muris cyst merozoites was expressed in a cell-free translation/translocation system to study translocation of the protein across membranes. The antigen was found to be translocated across heterologous endoplasmic reticulum membranes. Translocation was accompanied by cleavage of a signal peptide to create a 23-kDa polypeptide that was completely protected from digestion with proteinase K. Pulse-chase analysis of [35S]-methionine-labeled S. muris cyst merozoites demonstrated that the 16/17-kDa antigen derived from a 23-kDa precursor molecule and that its processing occurred at between a few minutes and 2 h after biosynthesis. This leads to the conclusion that the native microneme antigen is secreted from the parasite cell via the endoplasmic reticulum. Sorting into micronemes might occur during transition through a Golgi-like structure, involving cleavage of the hydrophilic propeptide to create the mature 16/17-kDa protein.

    Description / Table of Contents: Bestimmung der Spannungstensoren in dünnen, texturierten Kupferschichten mittels Röntgenbeugung bei streifendem EinfallIonenplattierte Kupferschichten wurden mittels Röntgenbeugung hinsichtlich Texturen und Eigenspannungen untersucht. Die vollständigen Orientierungsverteilungsfunktionen wurden bestimmt und scharfe (111)-Fasertexturen gefunden. Die Messung der Dehnungen erfolgte unter streifendem Strahleinfall. Zur Berechnung der Spannungstensoren wurden sowohl texturgewichtete elastische Moduln als auch texturunabhängige elastische Moduln verwendet. Die Bedeutung der Texturmessung für die Spannungstensorbestimmung wird diskutiert. Die gefundenen Spannungen können als thermisch verursacht verstanden werden.
    Notes: Ion-platted thin copper films were examined for residual stresses and texture by X-ray diffraction. The complete orientation distribution functions were determined and sharp (111)-fibre textures were found. The strains were measured by grazing incidence diffraction. The stress tensors were calculated using both texture-weighted elastic compliances and texture-independent X-ray elastic constants. The importance of the texture measurement for the stress tensor determination is discussed. The found stresses can be interpreted as thermally induced.
