nucleotide-binding domain (NBD) of the FGGY family of carbohydrate kinases; This family is predominantly composed of glycerol kinase (GK) and similar carbohydrate kinases including rhamnulokinase (RhuK), xylulokinase (XK), gluconokinase (GntK), ribulokinase (RBK), and fuculokinase (FK). These enzymes catalyze the transfer of a phosphate group, usually from ATP, to their carbohydrate substrates. The monomer of FGGY proteins contains two large domains, which are separated by a deep cleft that forms the active site. One domain is primarily involved in sugar substrate binding, and the other is mainly responsible for ATP binding. This model includes both the N-terminal domain, which adopts a ribonuclease H-like fold, and the structurally related C-terminal domain. Substrate-induced conformational changes and a divalent cation may be required for the catalytic activity. The FGGY family belongs to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily, all members of which share a common characteristic five-stranded beta sheet occurring in both the N- and C-terminal domains.

nucleotide-binding domain (NBD) of metazoan glycerol kinase 5 (GK5) and similar proteins; The subfamily corresponds to a group of metazoan putative glycerol kinases (GK), which may be coded by the GK-like gene, GK5. Sequence comparison shows members of this group are homologs of bacterial GKs, and they retain all functionally important residues. However, GK-like proteins in this family do not have detectable GK activity. The reason remains unclear. It has been suggested that the conserved catalytic residues might facilitate them performing a distinct function. GK5 is a skin-specific kinase expressed predominantly in sebaceous glands. It can form a complex with the sterol regulatory element-binding proteins (SREBPs) through their C-terminal regulatory domains, inhibiting SREBP processing and activation. GK5 also promotes gefitinib resistance by inhibiting apoptosis and cell cycle arrest. Members of this subfamily belong to the FGGY family of carbohydrate kinases, the monomers of which contain two large domains, which are separated by a deep cleft that forms the active site. This model includes both the N-terminal domain, which adopts a ribonuclease H-like fold, and the structurally related C-terminal domain.
