nucleotide-binding domain (NBD) of the first repeat of hexokinase domain-containing protein 1 (HKDC1) from metazoan hexokinase (HK) domain family; Hexokinase (EC 2.7.1.1) possesses the ability to transfer an inorganic phosphate group from ATP to a substrate. It catalyzes the ATP-dependent phosphorylation of aldo- and keto-hexose sugars to the hexose-6-phosphate (H6P). It can catalyze this reaction on glucose, fructose, sorbitol and glucosamine, and as such is the first step in a number of metabolic pathways. Hexokinase contains two structurally similar domains. Some members of the family have two copies of each of these domains. For example, members from vertebrates contain four hexokinase isozymes, designated I to IV, where types I to III contain a duplication of the two-domain yeast-type hexokinases. HKDC1 is a putative novel fifth hexokinase found in vertebrates. It may be involved in whole-body glucose use. The model corresponds to the first two domains of HKDC1. : Pssm-ID: 466976 [Multi-domain] Cd Length: 429 Bit Score: 888.81 E-value: 0e+00

ATPase-like domain of the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily; The ASKHA superfamily, also known as actin-like ATPase domain superfamily, includes acetate and sugar kinases, heat-shock cognate 70 (Hsp70) and actin family proteins. They either function as conformational hydrolases (e.g. Hsp70, actin) that perform simple ATP hydrolysis, or as metabolite kinases (e.g. glycerol kinase) that catalyze the transfer of a phosphoryl group from ATP to their cognate substrates. Both activities depend on the presence of specific metal cations. ASKHA superfamily members share a common core fold that includes an actin-like ATPase domain consisting of two subdomains (denoted I _ II) with highly similar ribonuclease (RNase) H-like folds. The fold of each subdomain is characterized by a central five strand beta-sheet and flanking alpha-helices. The two subdomains form an active site cleft in which ATP binds at the bottom. Another common feature of ASKHA superfamily members is the coupling of phosphoryl-group transfer to conformational rearrangement, leading to domain closure. Substrate binding triggers protein motion. The actual alignment was detected with superfamily member cd24130: Pssm-ID: 483947 [Multi-domain] Cd Length: 433 Bit Score: 427.04 E-value: 8.46e-143

Some members of the family have two copies of each of these domains. There are three isozymes of hexokinase in yeast (PI, PII and glucokinase): isozymes PI and PII phosphorylate both aldo- and keto-sugars; glucokinase (EC 2.7.1.2) is specific for aldo-hexoses. Early meiotic induction protein 2 (EMI2, also known as glucokinase-2, EC 2.7.1.2) might be another isozyme of hexokinase in yeast. It is a putative glucokinase that functions in phosphorylation of aldohexoses and glucose uptake. It is involved in sporulation and required for the full activation of the early meiotic inducer IME1. Yeast hexokinases reveal a well-defined catalytic pocket that binds ATP and hexose, allowing easy transfer of the phosphate from ATP to the sugar.

It catalyzes the ATP-dependent phosphorylation of aldo- and keto-hexose sugars to the hexose-6-phosphate (H6P). It can catalyze this reaction on glucose, fructose, sorbitol and glucosamine, and as such is the first step in a number of metabolic pathways. Hexokinase contains two structurally similar domains. Some members of the family have two copies of each of these domains. For example, members from vertebrates contain four hexokinase isozymes, designated I to IV, where types I to III contain a duplication of the two-domain yeast-type hexokinases.

nucleotide-binding domain (NBD) of fungal hexokinase (HK) domain family; Hexokinase (EC 2.7.1.1) possesses the ability to transfer an inorganic phosphate group from ATP to a substrate. It catalyzes the ATP-dependent phosphorylation of aldo- and keto-hexose sugars to the hexose-6-phosphate (H6P). It can catalyze this reaction on glucose, fructose, sorbitol and glucosamine, and as such is the first step in a number of metabolic pathways. Hexokinase contains two structurally similar domains. Some members of the family have two copies of each of these domains. There are three isozymes of hexokinase in yeast (PI, PII and glucokinase): isozymes PI and PII phosphorylate both aldo- and keto-sugars; glucokinase (EC 2.7.1.2) is specific for aldo-hexoses. Early meiotic induction protein 2 (EMI2, also known as glucokinase-2, EC 2.7.1.2) might be another isozyme of hexokinase in yeast. It is a putative glucokinase that functions in phosphorylation of aldohexoses and glucose uptake. It is involved in sporulation and required for the full activation of the early meiotic inducer IME1. Yeast hexokinases reveal a well-defined catalytic pocket that binds ATP and hexose, allowing easy transfer of the phosphate from ATP to the sugar.

Some members of the family have two copies of each of these domains. Hexokinases belong to the ASKHA (Acetate and Sugar Kinases/Hsc70/Actin) superfamily of phosphotransferases, 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 the first repeat of type III hexokinase from metazoan hexokinase (HK) domain family; Hexokinase (EC 2.7.1.1) possesses the ability to transfer an inorganic phosphate group from ATP to a substrate. It catalyzes the ATP-dependent phosphorylation of aldo- and keto-hexose sugars to the hexose-6-phosphate (H6P). It can catalyze this reaction on glucose, fructose, sorbitol and glucosamine, and as such is the first step in a number of metabolic pathways. Hexokinase contains two structurally similar domains. Some members of the family have two copies of each of these domains. For example, members from vertebrates contain four hexokinase isozymes, designated I to IV, where types I to III contain a duplication of the two-domain yeast-type hexokinases. Both the N- and C-terminal halves bind hexose and H6P. In types I and III only the C-terminal half supports catalysis. Their N-terminal half is the regulatory region. In type II, both halves support catalysis. Type IV hexokinase is similar to the yeast enzyme in containing only the two domains and is sometimes incorrectly referred to as glucokinase. Whereas types I to III can phosphorylate a variety of hexose sugars and are inhibited by glucose-6-phosphate (G6P), type IV is specific for glucose and shows no G6P inhibition. The model corresponds to the first two domains of type III hexokinase. Pssm-ID: 466940 [Multi-domain] Cd Length: 431 Bit Score: 219.79 E-value: 7.77e-64

Some members of the family have two copies of each of these domains. Hexokinases act as sugar sensors in higher plants. They may regulate sugar-dependent gene repression or activation. They mediate the effects of sugar on plant growth and development independently of its catalytic activity or the sugar metabolism. They may also regulate the execution of program cell death in plant cells, as well as promote roots and leaves growth.
