CC -!- FUNCTION: The phosphoenolpyruvate-dependent sugar phosphotransferase
CC system (sugar PTS), a major carbohydrate active -transport system,
CC catalyzes the phosphorylation of incoming sugar substrates
CC concomitantly with their translocation across the cell membrane. This
CC system is involved in alpha-glucoside transport.
CC {ECO:0000269|PubMed:11322729}.
CC -!- FUNCTION: Involved in the transport and simultaneous phosphorylation at
CC O-6 of the glucosyl moiety of sucrose and its five linkage-isomeric
CC alpha-D-glucosyl-D-fructoses. Can also transport maltose, isomaltose
CC and maltitol, phosphorylating at O-6 of their non-reducing glucose
CC portion. {ECO:0000269|PubMed:11322729}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- DOMAIN: The EIIC domain forms the PTS system translocation channel and
CC contains the specific substrate-binding site.
CC -!- DOMAIN: The EIIB domain is phosphorylated by phospho-EIIA on a
CC cysteinyl or histidyl residue, depending on the transported sugar.
CC Then, it transfers the phosphoryl group to the sugar substrate
CC concomitantly with the sugar uptake processed by the EIIC domain.
