Studies on the activities of ALPase, ACPase, ATPase and accumulation of volutin granules upon growth phase in saccharomyces uvarum
Saccharomyces uvarum의 배양시기에 따른 ALPase, ACPase, ATPase 활성도와 volutin과립 축적량
Abstract
The present study was designed to investigate cellular regulation of phosphate metabolism between catabolically repressed and derepressed states in yeast (Saccharomyces uvarum). The activities of various phospatases and the contents of phosphate compounds were detected according to the culture phase and various phosphate concentrations. As the results, Saccharomyces uvarum derepressed many phosphate metabolizing enzymes such as alkaline phosphatase, acid phosphatase and ATPase more than ten fold simultaneously during catabolic repression (phospgate and sugar starvation). At the same state, the amounts of orthophosphate, nucleotidic labile phosphate and acid soluble polypgosphate were increased, compared to basal levels of normally cultivated cells.
