Abstract ATP:guanido phosphotransferases are a family of structurally and functionally related enzymes [PubMed2324092, PubMed7819288] that reversibly catalyze the transfer of phosphate between ATP and various phosphogens. The enzymes belonging to this family include glycocyamine kinase , which catalyzes the transfer of phosphate from ATP to guanidoacetate; arginine kinase , which catalyzes the transfer of phosphate from ATP to arginine; taurocyamine kinase , an annelid-specific enzyme that catalyzes the transfer of phosphate from ATP to taurocyamine; lombricine kinase , an annelid-specific enzyme that catalyzes the transfer of phosphate from ATP to lombricine; Smc74, a cercaria-specific enzyme from Schistosoma mansoni [PubMed2324092]; and creatine kinase (CK) [PubMed3896131, PubMed2324105], which plays an important role in energy metabolism of vertebrates. It catalyzes the reversible transfer of high energy phosphate from ATP to creatine, generating phosphocreatine and ADP. There are at least four different, but very closely related, forms of CK. Two isozymes, M (muscle) and B (brain), are cytosolic, while the other two are mitochondrial. In sea urchins there is a flagellar isozyme, which consists of the triplication of a CK-domain. A cysteine residue is implicated in the catalytic activity of these enzymes and the region around this active site residue is highly conserved.

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 17 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Guanido kinase N-terminal domain domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 17 hidden Markov models representing the Guanido kinase N-terminal domain superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
