Guanylate kinase (EC 2.7.4.8) is an enzyme that catalyzes the chemical reaction

The reaction interconverts the nucleotide, guanosine monophosphate (GMP) and guanosine diphosphate (GDP) by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).[1] The enzyme has very widespread occurrence, for example in L cells,[2] Escherichia coli,[3][4] rat liver,[5] and calf thymus.[6]

Guanylate kinase is essential for recycling GMP and indirectly, cGMP. In prokaryotes (such as Escherichia coli), lower eukaryotes (such as yeast) and in vertebrates, it is a highly conserved monomeric protein of about 200 amino acids which has been shown to be structurally similar to protein A57R (or SalG2R) from various strains of Vaccinia virus.[7][8][9] Systems biology analyses carried out by the team of Andreas Dräger also identified a pivotal role of this enzyme in the replication of SARS-CoV-2 within the human airways.[10][11][12]

Nomenclature

[edit]

This enzyme is a transferase, specifically one transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:(d)GMP phosphotransferase. Other names in common use include"

  • deoxyguanylate kinase,
  • 5'-GMP kinase,
  • GMP kinase,
  • guanosine monophosphate kinase, and
  • ATP:GMP phosphotransferase.[13]
