N. Mathew et al., HUMAN DIADENOSINE 5',5'''-P-1,P-4-TETRAPHOSPHATE PYROPHOSPHOHYDROLASEIS A MEMBER OF THE MUTT FAMILY OF NUCLEOTIDE PYROPHOSPHATASES, Biochemical journal, 311, 1995, pp. 717-721
The cDNA and derived amino acid sequence of human diadenosine 5', 5'''
-P-1, P-4-tetraphosphate pyrophosphohydrolase have been determined wit
h the aid of the GenBank Expressed Sequence Tag database. This enzyme
possesses a modification of the MuT sequence motif found in certain nu
cleotide pyrophosphatases. It is unrelated to the enzymes of diadenosi
ne tetraphosphate catabolism found in prokaryotes and fungi.
