CC -!- FUNCTION: Converts seryl-tRNA(Sec) to selenocysteinyl-tRNA(Sec)
CC required for selenoprotein biosynthesis. {ECO:0000255|HAMAP-
CC Rule:MF_00423}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H(+) + L-seryl-tRNA(Sec) + selenophosphate = L-
CC selenocysteinyl-tRNA(Sec) + phosphate; Xref=Rhea:RHEA:22728,
CC Rhea:RHEA-COMP:9742, Rhea:RHEA-COMP:9743, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16144, ChEBI:CHEBI:43474, ChEBI:CHEBI:78533,
CC ChEBI:CHEBI:78573; EC=2.9.1.1; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00423};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00423};
CC -!- PATHWAY: Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec)
CC biosynthesis; selenocysteinyl-tRNA(Sec) from L-seryl-tRNA(Sec)
CC (bacterial route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_00423}.
CC -!- SUBUNIT: Homodecamer; pentamer of dimers. Binds only one seryl-
CC tRNA(Sec) per dimer. {ECO:0000255|HAMAP-Rule:MF_00423}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00423}.
CC -!- SIMILARITY: Belongs to the SelA family. {ECO:0000255|HAMAP-
CC Rule:MF_00423}.
