The uptake of Mn by Saccharomyces cerevisiae at the expense of endogenous sources of energy-depends on the stage of culture development and is maximum in the middle of the exponential phase. The ability of cells to take up Mn is related to the content of intracellular potassium at all stages of growth, to the content of ATP during the exponential phase and it is not related to the content of inorganic polyphosphates. The uptake is inhibited by oligomycin (25 μg/ml) by 50-85 % and under anaerobic conditions by 10-50 %, depending on the stage of growth, indicating the role of aerobic phosphorylation in the process. The uptake of Mn is apparently associated with a hydrolysis of low-molecular weight polyphosphates and ATP, as well as with the exit of K from cells. [ABSTRACT FROM AUTHOR] |
