CC   -!- FUNCTION: Key enzyme in the regulation of glycerol uptake and
CC       metabolism. Catalyzes the phosphorylation of glycerol to yield sn-
CC       glycerol 3-phosphate. {ECO:0000255|HAMAP-Rule:MF_00186}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + glycerol = ADP + H(+) + sn-glycerol 3-phosphate;
CC         Xref=Rhea:RHEA:21644, ChEBI:CHEBI:15378, ChEBI:CHEBI:17754,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:57597, ChEBI:CHEBI:456216;
CC         EC=2.7.1.30; Evidence={ECO:0000255|HAMAP-Rule:MF_00186};
CC   -!- ACTIVITY REGULATION: Activity of this regulatory enzyme is affected by
CC       several metabolites. Allosterically and non-competitively inhibited by
CC       fructose 1,6-bisphosphate (FBP) and unphosphorylated phosphocarrier
CC       protein EIIA-Glc (III-Glc), an integral component of the bacterial
CC       phosphotransferase (PTS) system. {ECO:0000255|HAMAP-Rule:MF_00186}.
CC   -!- PATHWAY: Polyol metabolism; glycerol degradation via glycerol kinase
CC       pathway; sn-glycerol 3-phosphate from glycerol: step 1/1.
CC       {ECO:0000255|HAMAP-Rule:MF_00186}.
CC   -!- SUBUNIT: Homotetramer and homodimer (in equilibrium). Heterodimer with
CC       EIIA-Glc. Binds 1 zinc ion per glycerol kinase EIIA-Glc dimer. The zinc
CC       ion is important for dimerization. {ECO:0000255|HAMAP-Rule:MF_00186}.
CC   -!- SIMILARITY: Belongs to the FGGY kinase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00186}.
