    Notes: Abstract A procedure has been developed to isolate and analyse the cell-wall glycoproteins of Chlamydomonas reinhardii. Under appropriate conditions, cell-wall glycoproteins can be quantitatively extracted from intact cells by aqueous LiCl. Although proteins and glycoproteins, which are presumably not related to the cell wall, are coextracted with the cell-wall subunits, these components can be readily identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis as demonstrated by comparative analysis of LiCl-extracts from wild-type cells and the cell-wall-deficient mutant CW-15. Apart from the high-molecular-weight cell-wall components, two glycoproteins with apparent molecular weights (Mrs) of 36000 and 66000 were found to be present in LiCl-extracts of wild-type cells but absent in LiCl-extracts from the cell-wall-less mutant. Pulse-labeling experiments with [3H]proline and [35S]methionine revealed that the LiCl-extracts contained — in addition to the well-known cell-wall subunits — proteins of lower molecular weight, which are also preferentially labeled with [3H]proline. Protein components with Mrs of 68000, 44000, 36000, 26000 and 22000 were found to be more strongly labeled with [3H]proline than with [35S]methionine, whereas protein components with Mrs of 57000 and 52000 were more prominent after labeling with [35S]methionine. The portion of cell-wall subunits within the total amount of proteins extracted by LiCl was calculated to be at least 10% on the basis of the amount of hydroxyproline. Self-assembly of cell walls could be demonstrated after dialysis against water of a mixture of crude LiCl-extract and purified, insoluble, inner wall layers. Cell-wall glycoproteins could be enriched by gel exclusion chromatography of crude LiCl-extracts on Sepharose CL-4B columns equilibrated with 1 mol l-1 LiCl.

    Notes: Zusammenfassung Das Bestrahlen von niedrigprozentigen Lösungen von AgNO3 und Ag2O, in denen Reduktionszentren irgendwelcher Herkunft fehlen, führt nicht zur Reduktion. Reinstes Gummiarabikum in 0,7 prozentiger Lösung und niedriger vermag weder für sich, noch auch vorbestrahlt reduzierend auf die Silberlösungen zu wirken. Das Bestrahlen eines Gemisches von beiden führt je nach der Wellenlänge des einwirkenden Lichtes entweder nur zur Reduktion mit Niederschlagsbildung (sichtbare) oder zur Solbildung (ultraviolette Strahlen). Dabei scheinen die Submikronen des Gummis in erster Linie als Reduktionszentren zu dienen. Im Gegensatz zu der reduzierenden und ausfällenden Wirkung der sichtbaren Strahlen scheinen die ultravioletten bei dieser Versuchsanordnung eine „peptisierende“ oder „aufladende“ Wirkung zu haben, wie auch aus dem Zerteilen von Niederschlägen hervorzugehen scheint. Es gelingt auch, durch ultraviolette Strahlen in Gegenwart.von Reduktionszentren, die nicht schutzkolloidartig zu wirken vermögen, Silbersole zu gewinnen.
