IMP 5'-nucleotidase activity
Definition
Target type: molecularfunction
Catalysis of the reaction: 5'-IMP + H2O = inosine + phosphate. [GOC:ai]
IMP 5'-nucleotidase is an enzyme that catalyzes the hydrolysis of inosine monophosphate (IMP) to inosine and inorganic phosphate. This reaction is essential for purine nucleotide metabolism, as it is the final step in the degradation of inosine and hypoxanthine. The enzyme is a hydrolase, specifically a phosphodiesterase, and it acts on the phosphodiester bond between the phosphate group and the 5'-hydroxyl group of the ribose moiety of IMP. The reaction mechanism involves the formation of a covalent intermediate between the enzyme and the substrate, followed by hydrolysis of the intermediate to release the products. IMP 5'-nucleotidase is found in a variety of tissues, including liver, spleen, erythrocytes, and brain. It is also present in some bacteria and viruses. The enzyme plays a role in a variety of cellular processes, including DNA replication, cell growth, and differentiation.'
