Bacterial PEP-dependent carbohydrate: phosphotransferase systems couple sensing and global control mechanisms.


The PEP-dependent carbohydrate:phosphotransferase systems (PTSs) of enteric bacteria constitute a complex sensory system which involves as its central element a PEP-dependent His-protein kinase (Enzyme I). As a unit, the PTS comprises up to 20 different transporters per cell which correspond to its chemoreceptors for PTS carbohydrates, and several targeting… (More)
