Superfamily 3.90.950.10
Functional Family Inosine triphosphate pyrophosphatase

Enzyme Information

3.6.1.9
Nucleotide diphosphatase.
based on mapping to UniProt Q9BY32
A nucleoside triphosphate + H(2)O = a nucleotide + diphosphate.
-!- The enzyme preferentially hydrolyzes ATP, but can also hydrolyze other nucleoside 5' triphosphates such as GTP, CTP, TTP and UTP to their corresponding monophosphates. -!- In vitro the enzyme also acts as a nucleotidohydrolase on ADP, NAD(+), NADP(+), FAD, and CoA. -!- Formerly EC 3.6.1.19.
