External concentration changes

SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".

The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.

Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...

Gene interaction networks and models of cation homeostasis in Saccharomyces cerevisiae

Experimental approaches to study the mechanism and ions involved in potassium uptake after long term potassium starvation.

The external potassium changes will be monitored by the MIFE and FLISE technique. This allows an estimation of internal potassium changes by determining an initial concentration.

The external pH changes will be monitored by the MIFE and FLISE technique. This allows an estimation of internal pH changes by determining an initial pH. pH changes will be also determined by using green fluorescent protein dyes. Relating the proton efflux and the change of internal pH allows an estimate of the proton buffering capacity.
