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 complex composed of PtsG and Crr is involved in glucose
CC       transport. {ECO:0000250|UniProtKB:P69783}.
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000250|UniProtKB:P69783};
CC       Note=Binds 1 zinc ion per glycerol kinase EIIA-Glc dimer. The zinc ion
CC       is important for dimerization. {ECO:0000250|UniProtKB:P69783};
CC   -!- SUBUNIT: Heterodimer with glycerol kinase (glpk).
CC       {ECO:0000250|UniProtKB:P69783}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
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:PRU00416}.
