FunFam 57: Ectonucleoside triphosphate diphosphohydrolase 4

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Nucleoside diphosphate phosphatase. [EC: 3.6.1.6]
A nucleoside diphosphate + H(2)O = a nucleoside phosphate + phosphate.
  • The enzyme, which appears to be limited to metazoa, acts on multiple nucleoside diphosphates as well as on D-ribose 5-diphosphate.
  • Specificity depends on species and isoform.

Nucleoside-triphosphate phosphatase. [EC: 3.6.1.15]
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.
