title: Human diadenosine 5',5"'-P1,P4-tetraphosphate pyrophosphohydrolase is a member of the MutT family of nucleotide pyrophosphatases.
abstract: The cDNA and derived amino acid sequence of human diadenosine 5',5"'-P1,P4-tetraphosphate pyrophosphohydrolase have been determined with the aid of the GenBank Expressed Sequence Tag database. This enzyme possesses a modification of the MutT sequence motif found in certain nucleotide pyrophosphatases. It is unrelated to the enzymes of diadenosine tetraphosphate catabolism found in prokaryotes and fungi.
