Taxonomic identifier

7955 [NCBI]

Taxonomic lineage

Protein attributes

Sequence length	392 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Synthesizes selenophosphate from selenide and ATP By similarity.
Catalytic activity	ATP + selenide + H2O = AMP + selenophosphate + phosphate.
Sequence similarities	Belongs to the selenophosphate synthase 1 family. Class II subfamily.
Caution	The conserved active site Cys (or selenocysteine) residue in position 29 is replaced by a Thr. However, as function in selenoprotein synthesis is probable, it is possible Cys-31 is the active site.
