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}.
