Catalysis of the reaction: 5'-GMP + H2O = guanosine + phosphate. [GOC:ai]
GMP 5'-nucleotidase activity is a hydrolytic enzyme that catalyzes the dephosphorylation of guanosine 5'-monophosphate (GMP) to guanosine. This reaction removes the phosphate group from the 5' position of GMP, releasing inorganic phosphate (Pi) and generating guanosine. GMP 5'-nucleotidase plays a crucial role in purine nucleotide metabolism, particularly in the salvage pathway for guanine. This pathway allows for the reutilization of guanine bases, which are essential components of DNA and RNA. In addition to its role in purine metabolism, GMP 5'-nucleotidase has also been implicated in various cellular processes, including signal transduction, cell proliferation, and immune responses. The enzyme is found in a wide range of organisms, from bacteria to humans. It is localized in various cellular compartments, including the cytoplasm, plasma membrane, and lysosomes. The activity of GMP 5'-nucleotidase is regulated by various factors, including pH, metal ions, and substrate concentration.'
