To investigate in-vivo concentrations of cytoplasmic phosphate, especially during dynamic conditions, a method has been developed that enables reproducible determination of cytopiasmic phosphate from 5 pM up to 30 FM. The method involves fast sampling. spontaneous inactivation of cell metabolism and

โฆ Synopsis
Orthophosphate concentration of baker's yeast Saccharomyces cerevisiae was investigated during dynamic conditions. As an example for those dynamics in cell metabolism the transition from glucose limitation to glucose excess (Crabtree-effect) was choosen. As a result of the metabolic switch from complete to partial oxidative metabolism, the cytoplasmic phosphate concentration increased suddenly from 8.4 mM to a maximum of 17.5 mM and transiently decreased to a minimum of 7.0 mM.

In the petite positive yeast, Saccharomyces cerevisiae, cycloheximide selectively inhibits protein synthesis on cytoplasmic ribosomes, and, as a consequence, nuclear DNA synthesis. Mitochondrial DNA, however, is synthesized for d~6 h after cessation of protein synthesis. In this paper we show that i
