The PEP:Sugar Phosphotransferase System

The PTS is a sugar transport system that couples the transport of a sugar to its phosphorylation. The phosphate group is derived from phosphoenolpyruvate (PEP) and transferred via the general PTS proteins Enzyme I (EI) and HPr to the substrate-specific Enzymes II (EII) to the incoming sugars.

In addition to its role in sugar transport, the PTS is also involved in the regulation of carbon metabolism.
