The phosphoenolpyruvate-dependent sugar phosphotransferase system (PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitant with their translocation across the cell membrane (By similarity). Involved in cellobiose transport with PtcA and PtcB. This system can also transport lactose (PubMed:17909747, PubMed:21262549). Induced by growth on cellobiose. Negativelly controled by the CcpA regulator. The EIIC type-3 domain forms the PTS system translocation channel and contains the specific substrate-binding site. Disruption of the gene abolishes growth on cellobiose and lactose.
