Since over 40 enzymes will be investigated for their mRNA abundance, processing, and degradation kinetics, the less tedious and more accurate Next Generation Sequencing of the entire mRNA repertoire of the cell is employed. To optimise the proportion of useful sequence, while including RNA fragments that are products of of degradation, rRNA is depleted using the eukaryotic Ribominus kit (Ambion). Two biological replicates are treated with Sinefungin and Actinomycin D to inhibit RNA processing and

Determination of essential amino acids for Streptococcus pyogenes M49

Mutant strains which carry deletions of important metabolic enzymes, as well as mutant strains with altered regulation, need to adapt by changing fluxes or gene expression to compensate with the absence/differed concentration of these key enzymes. This may give new insights in the regulation of these pathways/enzymes.

Parasites will be harvested at different growth phases and the total amount of the proteins will be followed by western blot. The absolut concentration will be obtained by comparison with a know amount of the recombinant untagged protein. The thiol redox state of the proteins will be followed by modification of the free cys with methoxy-ethyl-maleinimide poly(ethylenglycol) (Meo-PEG-mal).
