Phosphoenolpyruvate-Dependent Phosphotransferase System (PEP–PTS)

• The phosphotransferase system (PTS) is the best-known example of group translocation in bacteria.
• It transports sugars into the cell while simultaneously phosphorylating them.
• PEP–PTS is a bacterial transport system in which phosphoenolpyruvate (PEP) provides phosphate energy to transport sugars across the membrane.
