CC   -!- FUNCTION: The phosphoenolpyruvate-dependent sugar phosphotransferase
CC       system (PTS), a major carbohydrate active transport system, catalyzes
CC       the phosphorylation of incoming sugar substrates concomitant with their
CC       translocation across the cell membrane. The enzyme II complex composed
CC       of GatA, GatB and GatC is involved in galactitol transport. It can also
CC       use D-glucitol. {ECO:0000269|PubMed:1100608,
CC       ECO:0000269|PubMed:8955298}.
CC   -!- SUBUNIT: Forms a complex with one each of subunit of GatA, GatB and 2
CC       subunits of GatC. {ECO:0000269|PubMed:16079137}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305|PubMed:8955298}.
CC   -!- INDUCTION: Constitutively expressed. {ECO:0000269|PubMed:8955298}.
CC   -!- DOMAIN: The EIIA domain is phosphorylated by phospho-HPr on a histidyl
CC       residue. Then, it transfers the phosphoryl group to the EIIB domain.
CC       {ECO:0000255|PROSITE-ProRule:PRU00417}.
CC   -!- CAUTION: In strain W3110, the sequence is interrupted by the insertion
CC       of an IS5 element between positions 69 and 70. {ECO:0000305}.
