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 the uptake and phosphorylation of MurNAc-GlcNAc,
CC the principle peptidoglycan turnover product of S.aureus, yielding
CC cytoplasmic MurNAc 6P-GlcNAc. {ECO:0000269|PubMed:30524387}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=N(pros)-phospho-L-histidyl-[protein] + N-acetyl-beta-D-
CC muramate-(1->4)-N-acetyl-D-glucosamine(out) = 6-phospho-N-acetyl-
CC beta-D-muramate-(1->4)-N-acetyl-D-glucosamine(in) + L-histidyl-

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:66785;
CC Evidence={ECO:0000305|PubMed:30524387};
CC -!- PATHWAY: Cell wall biogenesis; peptidoglycan recycling.
CC {ECO:0000305|PubMed:30524387}.
CC -!- SUBCELLULAR LOCATION: Cell 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 -!- DOMAIN: The EIIC domain forms the PTS system translocation channel and
CC contains the specific substrate-binding site.
CC -!- DISRUPTION PHENOTYPE: Cells lacking this gene show an extracellular
CC accumulation of the disaccharide turnover product MurNAc-GlcNAc, but do
CC not accumulate MurNAc. {ECO:0000269|PubMed:30524387}.
