Protein names

Recommended name:
Selenide, water dikinase 1
EC=2.7.9.3

Alternative name(s):
Selenium donor protein 1
Selenophosphate synthase 1

Gene names

Name:

SEPHS1

Organism

Bos taurus (Bovine)

Taxonomic identifier

9913 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Laurasiatheria › Cetartiodactyla › Ruminantia › Pecora › Bovidae › Bovinae › Bos

Protein attributes

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

General annotation (Comments)

Function	Synthesizes selenophosphate from selenide and ATP By similarity.
Catalytic activity	ATP + selenide + H2O = AMP + selenophosphate + phosphate.
Subunit structure	Homodimer By similarity.
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.
