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 (By similarity).
CC   -!- CATALYTIC ACTIVITY: ATP + glycerol = ADP + sn-glycerol 3-
CC       phosphate.
CC   -!- ENZYME REGULATION: Activity of this regulatory enzyme is affected
CC       by several metabolites. Allosterically and non-competitively
CC       inhibited by fructose 1,6-bisphosphate (FBP) and unphosphorylated
CC       phosphocarrier protein EIIA-Glc (III-Glc), an integral component
CC       of the bacterial phosphotransferase (PTS) system (By similarity).
CC   -!- PATHWAY: Polyol metabolism; glycerol degradation via glycerol
CC       kinase pathway; sn-glycerol 3-phosphate from glycerol: step 1/1.
CC   -!- SUBUNIT: Homotetramer and homodimer (in equilibrium). Heterodimer
CC       with EIIA-Glc. Binds 1 zinc ion per glycerol kinase EIIA-Glc
CC       dimer. The zinc ion is important for dimerization (By similarity).
CC   -!- SIMILARITY: Belongs to the FGGY kinase family.
