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 LacEF PTS system is involved in lactose transport.
CC       {ECO:0000250|UniProtKB:P0A0D6}.
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:P23532};
CC       Note=Binds 1 Mg(2+) ion per trimer. {ECO:0000250|UniProtKB:P23532};
CC   -!- SUBUNIT: Homotrimer. {ECO:0000250|UniProtKB:P0A0D6}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- INDUCTION: Induced by lactose, galactose and galactose-6-P. Repressed
CC       by glucose. {ECO:0000250|UniProtKB:P0A0D6}.
CC   -!- DOMAIN: The PTS EIIA type-3 domain is phosphorylated by phospho-HPr on
CC       a histidyl residue. Then, it transfers the phosphoryl group to the PTS
CC       EIIB type-3 domain. {ECO:0000255|PROSITE-ProRule:PRU00418}.
