nucleotide-binding domain (NBD) of Homo sapiens xylulose kinase (XK) and similar proteins; XK (EC 2.7.1.17), also called xylulokinase or D-xylulose kinase, catalyze the rate-limiting step in the ATP-dependent phosphorylation of D-xylulose to produce D-xylulose 5-phosphate (X5P), a molecule that may play an important role in the regulation of glucose metabolism and lipogenesis. The subfamily includes XKs mainly from eukaryote. They 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.

nucleotide-binding domain (NBD) of Escherichia coli xylulose kinase (EcXK) and similar proteins; The subfamily contains a group of uncharacterized proteins with similarity to Escherichia coli xylulose kinase (EcXK). XK (EC 2.7.1.17), also called xylulokinase or D-xylulose kinase, catalyze the rate-limiting step in the ATP-dependent phosphorylation of D-xylulose to produce D-xylulose 5-phosphate (X5P), a molecule that may play an important role in the regulation of glucose metabolism and lipogenesis. EcXK, also known as 1-deoxy-D-xylulokinase, can also catalyze the phosphorylation of 1-deoxy-D-xylulose to 1-deoxy-D-xylulose 5-phosphate, with lower efficiency. It can also use D-ribulose, xylitol and D-arabitol, but D-xylulose is preferred over the other substrates. EcXK has a weak substrate-independent Mg-ATP-hydrolyzing activity. 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.

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.

It phosphorylates the ring-open form of (S)-4,5-dihydroxypentane-2,3-dione (DPD), which is the precursor to all AI-2 signaling molecules, at the C5 position.

Unlike Escherichia coli GntK, which belongs to the superfamily of P-loop containing nucleoside triphosphate hydrolases, Members of this subfamily are homologous to glycerol kinase, xylulose kinase, and rhamnulokinase from Escherichia coli.

EcLyxK catalyzes the phosphorylation of L-xylulose and 3-keto-L-gulonate. It is involved in L-lyxose utilization via xylulose and may also be involved in the utilization of 2,3-diketo-L-gulonate. PmLyX catalyzes the phosphorylation of L-xylulose only. BaEryA catalyzes the phosphorylation of erythritol to D-erythritol-1-phosphate.

Both kinases exhibit ATP hydrolysis without substrate and can phosphorylate D-ribulose. They belong to the ribulokinase-like carbohydrate kinases, a subfamily of FGGY family carbohydrate kinases.

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.

nucleotide-binding domain (NBD) of glycerol kinase (GK) and similar proteins; GK (EC 2.7.1.30), also called ATP:glycerol 3-phosphotransferase, or glycerokinase, is a key enzyme in the regulation of glycerol uptake and metabolism. It catalyzes the Mg-ATP-dependent phosphorylation of glycerol to yield sn-glycerol 3-phosphate. It also catalyzes the phosphorylation of dihydroxyacetone, L-glyceraldehyde and D-glyceraldehyde. The subfamily includes GKs and GK-like proteins from all three kingdoms of living organisms. Metazoan GKs, coded by X chromosome-linked GK genes, and GK-like proteins, coded by autosomal testis-specific GK-like genes GK2, GK3 and Gykl1 (in mouse) are closely related to the bacterial GKs. The metazoan GKs do have GK enzymatic activity. However, the GK-like metazoan proteins do not exhibit GK activity and their biological functions are not yet clear. Some of them lack important functional residues involved in the binding of ADP and Mg2+, which may result in the loss of GK catalytic function. Others that have conserved catalytic residues have lost their GK activity as well; the reason remains unclear. It has been suggested the conserved catalytic residues might facilitate them performing a distinct function. Under different conditions, GKs from different species may exist in different oligomeric states. 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.
