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. HAMAP MF_00176
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. HAMAP MF_00176
Subcellular location	Cytoplasm By similarity HAMAP MF_00176.
Domain	Consists of two distinct domains, a catalytic core and a N-terminal extension that is involved in tRNA binding By similarity. HAMAP MF_00176
Sequence similarities	Belongs to the class-II aminoacyl-tRNA synthetase family. Type-1 seryl-tRNA synthetase subfamily.
