| Abstract | The effect of exogenous phosphate supply on the regulation of phosphate metabolism was investigated during catabolic repression and catabolic derepression in yeast (Saccharomyces uvarum). As the results, when sugar was supplemented in cells cultivated under phosphate free, the growith rate was low but it was capable of cell division. Polyphosphate "B" was accumulated highly in proportion to amount of phosphate added to the medium. Without regard to phosphate supply of the medium, the total amount of polyphospgate was almost similar, although each polyphosphate was turned over. Activities of all phosphatases remained continuously high in the cells cultivated in the phosphate free medium. Especially under catabolic repression, the function of polyphosphate system was shown to compensate the ATP/ADP system as phosphate donor, energy source and regulator. | ||
