Selenide, water dikinase

From Wikipedia, the free encyclopedia

In enzymology, a selenide, water dikinase (EC 2.7.9.3) is an enzyme that catalyzes the chemical reaction

ATP + selenide + H₂O 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, specifically those transferring phosphorus-containing groups (phosphotransferases) with paired acceptors. The systematic name of this enzyme class is ATP:selenide, water phosphotransferase. This enzyme is also called selenophosphate synthase. This enzyme participates in selenoamino acid metabolism.
