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.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Single-pass membrane
CC       protein {ECO:0000305}.
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.
