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}.
