Enzyme Information

3.6.1.15

Nucleoside-triphosphate phosphatase.

based on mapping to UniProt P11125

NTP + H(2)O = NDP + phosphate.

-!- The enzyme is found in eukaryotes and thermophilic bacteria, but appears to be absent from mesophilic bacteria. -!- Also hydrolyzes nucleoside diphosphates, thiamine diphosphate and FAD. -!- The enzyme from the plant Pisum sativum (garden pea) is regulated by calmodulin.
