The phosphoenolpyruvate-dependent sugar phosphotransferase system (sugar PTS), a major carbohydrate active transport system, catalyzes the phosphorylation of incoming sugar substrates concomitantly with their translocation across the cell membrane (By similarity). Involved in galactose transport with PtcA and Lmg_0963 (PubMed:30123211). D-galactose(out) + N(pros)-phospho-L-histidyl-[protein] = D-galactose 6-phosphate(in) + L-histidyl-[protein] Induced by growth on galactose. The PTS EIIB type-3 domain is phosphorylated by phospho-EIIA on a cysteinyl residue. Then, it transfers the phosphoryl group to the sugar substrate concomitantly with the sugar uptake processed by the PTS EIIC type-3 domain.
