CC -!- FUNCTION: Multifunctional protein that includes general (non sugar-
CC specific) and sugar-specific components of the phosphoenolpyruvate-
CC dependent sugar phosphotransferase system (sugar PTS). This major
CC carbohydrate active transport system catalyzes the phosphorylation of
CC incoming sugar substrates concomitantly with their translocation across
CC the cell membrane. The enzyme II FryABC PTS system is involved in
CC fructose transport. {ECO:0000250|UniProtKB:P77439}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-histidyl-[protein] + phosphoenolpyruvate = N(pros)-phospho-
CC L-histidyl-[protein] + pyruvate; Xref=Rhea:RHEA:23880, Rhea:RHEA-
CC COMP:9745, Rhea:RHEA-COMP:9746, ChEBI:CHEBI:15361, ChEBI:CHEBI:29979,
CC ChEBI:CHEBI:58702, ChEBI:CHEBI:64837; EC=2.7.3.9;
CC Evidence={ECO:0000250|UniProtKB:P08839};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-fructose(out) + N(pros)-phospho-L-histidyl-[protein] = D-
CC fructose 1-phosphate(in) + L-histidyl-[protein];

CC ChEBI:CHEBI:64837; EC=2.7.1.202;
CC Evidence={ECO:0000250|UniProtKB:P20966};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P08839};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- DOMAIN: The PTS EIIA type-2 domain is phosphorylated by phospho-HPr on
CC a histidyl residue. Then, it transfers the phosphoryl group to the PTS
CC EIIB type-2 domain. {ECO:0000255|PROSITE-ProRule:PRU00417}.
CC -!- DOMAIN: In contrast to classical PTS systems, the fructose-like PTS has
CC no requirement for HPr and Enzyme I; FryA combines a IIA domain with an
CC Enzyme I and a HPr domains. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the PEP-utilizing enzyme family. {ECO:0000305}.
