Selenide, water dikinase

In enzymology, a selenide, water dikinase is an enzyme that catalyzes the chemical reaction


 * ATP + selenide + H2O $$\rightleftharpoons$$ AMP + selenophosphate + phosphate

The 3 substrates of this enzyme are ATP, selenide, and H2O, whereas its 3 products are AMP, selenophosphate, and phosphate.

This enzyme belongs to the family of transferases, to be specific, those transferring phosphorus-containing groups (phosphotransferases) with paired acceptors (dikinases). The systematic name of this enzyme class is ATP:selenide, water phosphotransferase. This enzyme is also called selenophosphate synthetase. This enzyme participates in selenoamino acid metabolism.
