Protein attributes

Sequence length	424 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the attachment of serine to tRNA(Ser). Is also 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.
Catalytic activity	ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser). HAMAP MF_00176 ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec). HAMAP MF_00176
Pathway	Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec) biosynthesis; L-seryl-tRNA(Sec) from L-serine and tRNA(Sec): step 1/1. HAMAP MF_00176
Subunit structure	Homodimer. The tRNA molecule binds across the dimer By similarity.
Subcellular location	Cytoplasm By similarity.
Domain	Consists of two distinct domains, a catalytic core and a N-terminal extension that is involved in tRNA binding By similarity.
Sequence similarities	Belongs to the class-II aminoacyl-tRNA synthetase family. Type-1 seryl-tRNA synthetase subfamily.
