CC -!- FUNCTION: Catalyzes the attachment of serine to tRNA(Ser). Is also
CC probably able to aminoacylate tRNA(Sec) with serine, to form the
CC misacylated tRNA L-seryl-tRNA(Sec), which will be further converted
CC into selenocysteinyl-tRNA(Sec). {ECO:0000269|PubMed:9030733}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-serine + tRNA(Ser) = AMP + diphosphate + H(+) + L-
CC seryl-tRNA(Ser); Xref=Rhea:RHEA:12292, Rhea:RHEA-COMP:9669,

CC ChEBI:CHEBI:78533, ChEBI:CHEBI:456215; EC=6.1.1.11;
CC -!- PATHWAY: Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec)
CC biosynthesis; L-seryl-tRNA(Sec) from L-serine and tRNA(Sec): step 1/1.
CC -!- SUBUNIT: Homodimer. The tRNA molecule binds across the dimer (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- DOMAIN: Consists of two distinct domains, a catalytic core and a N-
CC terminal extension that is involved in tRNA binding. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC Type-1 seryl-tRNA synthetase subfamily. {ECO:0000305}.
