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 UlaABC PTS system is involved in ascorbate transport.
CC {ECO:0000250|UniProtKB:P69822}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-ascorbate(out) + N(pros)-phospho-L-histidyl-[protein] = L-
CC ascorbate 6-phosphate(in) + L-histidyl-[protein];
CC Xref=Rhea:RHEA:42436, Rhea:RHEA-COMP:9745, Rhea:RHEA-COMP:9746,
CC ChEBI:CHEBI:29979, ChEBI:CHEBI:38290, ChEBI:CHEBI:61698,
CC ChEBI:CHEBI:64837; EC=2.7.1.194;
CC Evidence={ECO:0000250|UniProtKB:P69822};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- INDUCTION: Induced by L-ascorbate. Repressed by UlaR.
CC {ECO:0000250|UniProtKB:P69822}.
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}.
