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 FryABC PTS system is involved in fructose transport.
CC       {ECO:0000250|UniProtKB:P20966}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-fructose(out) + N(pros)-phospho-L-histidyl-[protein] = D-
CC         fructose 1-phosphate(in) + L-histidyl-[protein];
CC         Xref=Rhea:RHEA:49252, Rhea:RHEA-COMP:9745, Rhea:RHEA-COMP:9746,
CC         ChEBI:CHEBI:29979, ChEBI:CHEBI:37721, ChEBI:CHEBI:58674,
CC         ChEBI:CHEBI:64837; EC=2.7.1.202;
CC         Evidence={ECO:0000250|UniProtKB:P20966};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
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}.
