Identification
BMDB Protein ID BMDBP00508
Secondary Accession Numbers None
Name Inosine triphosphate pyrophosphatase
Synonyms Not Available
Gene Name ITPA
Protein Type Enzyme
Biological Properties
General Function Nucleotide transport and metabolism
Specific Function Pyrophosphatase that hydrolyzes the non-canonical purine nucleotides inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) as well as 2'-deoxy-N-6-hydroxylaminopurine triposphate (dHAPTP) and xanthosine 5'-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions.
