 Title    Concentrations of W ild -T y p e and a Macrotetrolide Negative Mutant of Streptomyces griseus  
 Abstract    The studied macrotetrolide negative mutant of Streptomyces griseus showed a different spe­ cificity of potassium accumulation than the macrotetrolide producing wild-type, indicating, that the macrotetrolides may be part of the physiological potassium carrier.

 Title    Initiation in einem Polyribosomen-abhängigen Protein-synthetisierenden zellfreien System aus Saccharomyces Initiation in a Polyribosome-Dependent Protein-Synthesizing Cell-Free System from Saccharomyces  
 Abstract    A method to prepare polyribosomes from yeasts by using the french-press is described. The highest yield of polyribosomes was derived from late log-phase cells. These polyribosomes, in­ cubated in a cell-free system, were able to reinitiate protein synthesis, which was shown by in­ hibiting aminoacid incorporation by aurintricarboxylic acid, edeine and sodiumfluoride. W e de­ veloped the translational system in order to look for the optimal ion-conditions of a DNA-dependent protein-synthesizing system. W e found out that at the optimal MgCL-concentration (6 mM) protein synthesis was strongly inhibited by Mangan ions which are required for transcription in yeast. If protein-synthesis was carried out with 2 mM and 3 mM M gCU maximal aminoacid incorporation was observed at 2 mM and 1.5 mM M nCl2 .
