A rough scheme of the interactions of the PTS. The degree of phosphorylation of the PTS proteins is influenced by the flux through glycolysis and the overall concentration of the proteins. The respective genes are subject to transcriptional control by several transcriptions factors, e.g. Mlc and Crp and post-transcriptional control (not shown). The degree of phosphorylation of EIIACrris furthermore influenced by interactions with other proteins (L) during inducer exclusion. In case of a PTS sugar, the phosphoryl group from EIIACrris transferred to the transported sugar. E.g. glucose appears as glucose 6-phosphate inside the cell.
