− | =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 [[ptsI|Enzyme I]] ([[ptsI|EI]]) and [[ptsH|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.'''
