Protein attributes

Sequence length	454 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Catalyzes the attachment of serine to tRNA(Ser). Is also probably able to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-seryl-tRNA(Sec), which will be further converted into selenocysteinyl-tRNA(Sec) By similarity. UniProtKB Q9N0F3
Catalytic activity	ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser). UniProtKB Q9N0F3 ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec). UniProtKB Q9N0F3
Pathway	Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec) biosynthesis; L-seryl-tRNA(Sec) from L-serine and tRNA(Sec): step 1/1. UniProtKB Q9N0F3
Subunit structure	Homodimer. The tRNA molecule probably binds across the dimer By similarity. UniProtKB Q9N0F3
Subcellular location	Mitochondrion matrix Ref.2 UniProtKB Q9N0F3.
Domain	Consists of two distinct domains, a catalytic core and a N-terminal extension that is involved in tRNA binding By similarity. UniProtKB P0A8L1
Sequence similarities	Belongs to the class-II aminoacyl-tRNA synthetase family. Type-1 seryl-tRNA synthetase subfamily.
