7.4.8 from EC) (GK) [] catalyzes the ATP-dependent phosphorylation of GMP into GDP. It is essential for recycling GMP and indirectly, cGMP. In prokaryotes (such as Escherichia coli), lower eukaryotes (such as yeast) and in vertebrates, GK is a highly conserved monomeric protein of about 200 amino acids. GK has been shown [, , ] to be structurally similar to protein A57R (or SalG2R) from various strains of Vaccinia virus. Proteins containing one or more copies of the DHR domain, an SH3 domain as well as a C-terminal GK-like domain, are collectively termed MAGUKs (membrane-associated guanylate kinase homologs) [], and include Drosophila lethal(1)discs large-1 tumor suppressor protein (gene dlg1); mammalian tight junction protein Zo-1; a family of mammalian synaptic proteins that seem to interact with the cytoplasmic tail of NMDA receptor subunits (SAP90/PSD-95, CHAPSYN-110/PSD-93, SAP97/DLG1 and SAP102); vertebrate 55kDa erythrocyte membrane protein (p55); Caenorhabditis elegans protein lin-2; rat protein CASK; and human proteins DLG2 and DLG3. There is an ATP-binding site (P-loop) in the N-terminal section of GK, which is not conserved in the GK-like domain of the above proteins. However these proteins retain the residues known, in GK, to be involved in the binding of GMP.; GO: 0005515 protein binding; PDB: 3UAT_A 3KFV_A 2ANC_F 2F3T_E 2ANB_A 2AN9_A 1S96_A 2F3R_B 3TR0_A 1LVG_A ....

Active enzymes catalyze ATP-dependent phosphorylation of GMP to GDP. Structure resembles that of adenylate kinase. So-called membrane-associated guanylate kinase homologues (MAGUKs) do not possess guanylate kinase activities; instead at least some possess protein-binding functions.

7.4.8), also known as guanylate kinase (GKase), catalyzes the reversible phosphoryl transfer from adenosine triphosphate (ATP) to guanosine monophosphate (GMP) to yield adenosine diphosphate (ADP) and guanosine diphosphate (GDP). It plays an essential role in the biosynthesis of guanosine triphosphate (GTP). This enzyme is also important for the activation of some antiviral and anticancer agents, such as acyclovir, ganciclovir, carbovir, and thiopurines.

Members of this family resemble PhnN of phosphonate utilization operons, where different such operons confer the ability to use somewhat different profiles of C-P bond-containing compounds (see PubMed:15231805), including phosphites as well as phosphonates. PhnN in E. coli shows considerable homology to guanylate kinases (EC 2.7.4.8), and has actually been shown to act as a ribose 1,5-bisphosphokinase (PRPP forming). This suggests an analogous kinase reaction for phosphonate metabolism, converting 5-phosphoalpha-1-(methylphosphono)ribose to methylphosphono-PRPP.
