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. This
CC system is involved in N-acetylmuramic acid (MurNAc) transport, yielding
CC cytoplasmic MurNAc-6-P. Is also able to take up anhydro-N-acetylmuramic
CC acid (anhMurNAc), but cannot phosphorylate the carbon 6, probably
CC because of the 1,6-anhydro ring. {ECO:0000250|UniProtKB:P77272}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=N(pros)-phospho-L-histidyl-[protein] + N-acetyl-beta-D-
CC muramate(out) = L-histidyl-[protein] + N-acetyl-beta-D-muramate 6-
CC phosphate(in); Xref=Rhea:RHEA:33399, Rhea:RHEA-COMP:9745, Rhea:RHEA-

CC ChEBI:CHEBI:64848; EC=2.7.1.192;
CC Evidence={ECO:0000250|UniProtKB:P77272};
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|PROSITE-
CC ProRule:PRU00426}; Multi-pass membrane protein {ECO:0000255|PROSITE-
CC ProRule:PRU00426}.
CC -!- DOMAIN: The EIIB domain is phosphorylated by phospho-EIIA on a
CC cysteinyl or histidyl residue, depending on the transported sugar.
CC Then, it transfers the phosphoryl group to the sugar substrate
CC concomitantly with the sugar uptake processed by the EIIC domain.
CC {ECO:0000255|PROSITE-ProRule:PRU00421}.
CC -!- DOMAIN: The EIIC domain forms the PTS system translocation channel and
CC contains the specific substrate-binding site. {ECO:0000255|PROSITE-
CC ProRule:PRU00426}.
