Selenide, water dikinase 1 is an enzyme that in humans is encoded by the SEPHS1 gene.^[5][6]

This protein functions as an enzyme that synthesizes selenophosphate from selenide and ATP. Selenophosphate is the selenium donor used to synthesize selenocysteine, which is co-translationally incorporated into selenoproteins at in-frame UGA codons.^[6]
