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. The
CC enzyme II CmtAB PTS system is involved in D-mannitol transport.
CC {ECO:0000250|UniProtKB:P28008}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-mannitol(out) + N(pros)-phospho-L-histidyl-[protein] = D-
CC mannitol 1-phosphate(in) + L-histidyl-[protein];
CC Xref=Rhea:RHEA:33363, Rhea:RHEA-COMP:9745, Rhea:RHEA-COMP:9746,
CC ChEBI:CHEBI:16899, ChEBI:CHEBI:29979, ChEBI:CHEBI:61381,
CC ChEBI:CHEBI:64837; EC=2.7.1.197;
CC Evidence={ECO:0000250|UniProtKB:P00550,
CC ECO:0000250|UniProtKB:P28008};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|PROSITE-
CC ProRule:PRU00427}; Multi-pass membrane protein {ECO:0000255|PROSITE-
CC ProRule:PRU00427}.
CC -!- DOMAIN: The EIIC type-2 domain forms the PTS system translocation
CC channel and contains the specific substrate-binding site.
CC {ECO:0000255|PROSITE-ProRule:PRU00427}.
CC -!- DOMAIN: The PTS EIIB type-2 domain is phosphorylated by phospho-EIIA on
CC a cysteinyl residue. Then, it transfers the phosphoryl group to the
CC sugar substrate concomitantly with the sugar uptake processed by the
CC PTS EIIC type-2 domain. {ECO:0000255|PROSITE-ProRule:PRU00422}.
