How does internal potassium change (/decrease) during several hours of potassium starvation.
How does internal potassium changes (decreases) during several hours of potassium starvation. Is there a limit for internal potassium decrease? Sampling potassium content in cells during starvation The relative membrane potential will be measured according to the conditions of Navarrete et al. (2010). Various mutants will be tested for their effect. To estimate the relative changes of plasma-membrane potential, the diSC3(3) fluorescent probe was used and the changes in cell fluorescence monitored during 5 hours of incubation in YNB-F growth media without added potassium.

I created this for all SysMo Modellers
http://www.semanticsbml.org/aym Annotate Your Model
There you can annotate your non SBML models with biological terms (MIRIAM annotations). As a cool extra you can view you model source code with inserted biological infomation.
Together with this http://www.semanticsbml.org/semanticSBML you can serach for similar BioModels. The similarity search is based on MIRIAM annotations that are attached to you model. AYM also allows you to create annotations without ...
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 ...

Experimental approaches to evaluate cellular response to Potassium limitation. For this purpose, a series of isogenic strains derived from BY4741 and lacking one (TRK1 or TRK2) or both TRK genes encoding specific potassium uptake systems was constructed using the homologous recombination and Cre-lox system.
