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 ManXYZ PTS system is involved in mannose transport.
CC {ECO:0000250|UniProtKB:P69797}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=D-mannose(out) + N(pros)-phospho-L-histidyl-[protein] = D-
CC mannose 6-phosphate(in) + L-histidyl-[protein]; Xref=Rhea:RHEA:49232,

CC ChEBI:CHEBI:29979, ChEBI:CHEBI:58735, ChEBI:CHEBI:64837;
CC EC=2.7.1.191; Evidence={ECO:0000250|UniProtKB:P69797};
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P69797}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P69797}. Cell
CC inner membrane {ECO:0000250|UniProtKB:P69797}; Peripheral membrane
CC protein {ECO:0000250|UniProtKB:P69797}.
CC -!- DOMAIN: The PTS EIIA type-4 domain is phosphorylated by phospho-HPr on
CC a histidyl residue. Then, it transfers the phosphoryl group to the PTS
CC EIIB type-4 domain. {ECO:0000250|UniProtKB:P69797, ECO:0000305}.
CC -!- DOMAIN: The PTS EIIB type-4 domain is phosphorylated by phospho-EIIA on
CC a histidyl residue. Then, it transfers the phosphoryl group to the
CC sugar substrate concomitantly with the sugar uptake processed by the
CC PTS EIIC type-4 domain. {ECO:0000255|PROSITE-ProRule:PRU00424}.
