ATP--guanido phosphotransferase reversibly catalyzes the transfer of phosphate between ATP and various phosphogens; similar to arginine kinase that catalyzes the reversible transfer of the terminal phosphoryl group of ATP to L-arginine, and taurocyamine kinase that catalyzes the transfer of phosphate between ATP and various phosphogens (e.g. creatine phosphate)

Phosphagen (guanidino) kinases such as arginine kinase and similar enzymes; Eukaryotic arginine kinase-like phosphagen (guanidino) kinases are enzymes that transphosphorylate a high energy phosphoguanidino compound, like phosphoarginine in the case of arginine kinase (AK), which is used as an energy-storage and -transport metabolite, to ADP, thereby creating ATP. The substrate binding site is located in the cleft between the N and C-terminal domains, but most of the catalytic residues are found in the larger C-terminal domain. Besides AK, one of the most studied members of this family, this model also represents a phosphagen kinase with different substrate specificity, hypotaurocyamine kinase (HTK).

Phosphagen (guanidino) kinases mostly found in eukaryotes; Phosphagen (guanidino) kinases are enzymes that transphosphorylate a high energy phosphoguanidino compound, like phosphocreatine (PCr) in the case of creatine kinase (CK) or phosphoarginine in the case of arginine kinase, which is used as an energy-storage and -transport metabolite, to ADP, thereby creating ATP. The substrate binding site is located in the cleft between the N and C-terminal domains, but most of the catalytic residues are found in the larger C-terminal domain. In higher eukaryotes, CK exists in tissue-specific (muscle, brain), as well as compartment-specific (mitochondrial and cytosolic) isoforms. They are either coupled to glycolysis (cytosolic form) or oxidative phosphorylation (mitochondrial form). Besides CK and AK, the most studied members of this family are also other phosphagen kinases with different substrate specificities, like glycocyamine kinase (GK), lombricine kinase (LK), taurocyamine kinase (TK) and hypotaurocyamine kinase (HTK).

The substrate binding site is located in the cleft between the N and C-terminal domains, but most of the catalytic residues are found in the larger C-terminal domain. In higher eukaryotes, CKs are found as tissue-specific (muscle, brain), as well as compartment-specific (mitochondrial, cytosolic, and flagellar) isoforms. Mitochondrial and cytoplasmic CKs are dimeric or octameric, while the flagellar isoforms are trimers with three CD domains fused as a single protein chain. CKs are either coupled to glycolysis (cytosolic form) or oxidative phosphorylation (mitochondrial form). Besides CK, one of the most studied members of this family, this model also represents other phosphagen kinases with different substrate specificities, like glycocyamine kinase (GK), lombricine kinase (LK), taurocyamine kinase (TK), and echinoderm arginine kinase (AK).

Phosphagen (guanidino) kinases found in bacteria; Phosphagen (guanidino) kinases are enzymes that transphosphorylate a high energy phosphoguanidino compound, such as phosphocreatine (PCr) or phosphoarginine, which is used as an energy-storage and -transport metabolite, to ADP, thereby creating ATP. This subfamily is specific to bacteria and lacks an N-terminal domain, which otherwise forms part of the substrate binding site. Most of the catalytic residues are found in the larger C-terminal domain, however, which appears conserved in these bacterial proteins. Their functions have not been characterized.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
if a domain or superfamily has been annotated with functional sites (conserved features),
they are mapped to the query sequence and indicated through sets of triangles
with the same color and shade of the domain or superfamily that provides the annotation. Mouse over the colored bars or triangles to see descriptions of the domains and features.
