CC -!- FUNCTION: Catalyzes the attachment of serine to tRNA(Ser). Is also able
CC to aminoacylate tRNA(Sec) with serine, to form the misacylated tRNA L-
CC seryl-tRNA(Sec), which will be further converted into selenocysteinyl-
CC tRNA(Sec). {ECO:0000255|HAMAP-Rule:MF_00176}.
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 Evidence={ECO:0000255|HAMAP-Rule:MF_00176};
CC -!- PATHWAY: Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec)
CC biosynthesis; L-seryl-tRNA(Sec) from L-serine and tRNA(Sec): step 1/1.
CC {ECO:0000255|HAMAP-Rule:MF_00176}.
CC -!- SUBUNIT: Homodimer. The tRNA molecule binds across the dimer.
CC {ECO:0000255|HAMAP-Rule:MF_00176}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00176}.
CC -!- DOMAIN: Consists of two distinct domains, a catalytic core and a N-
CC terminal extension that is involved in tRNA binding.
CC {ECO:0000255|HAMAP-Rule:MF_00176}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC Type-1 seryl-tRNA synthetase subfamily. {ECO:0000255|HAMAP-
CC Rule:MF_00176}.
