CC -!- FUNCTION: Converts O-phosphoseryl-tRNA(Sec) to selenocysteinyl-
CC tRNA(Sec) required for selenoprotein biosynthesis.
CC {ECO:0000256|ARBA:ARBA00002552, ECO:0000256|PIRNR:PIRNR017689}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-seryl-tRNA(Sec) + selenophosphate = L-
CC selenocysteinyl-tRNA(Sec) + 2 phosphate; Xref=Rhea:RHEA:25041,
CC Rhea:RHEA-COMP:9743, Rhea:RHEA-COMP:9947, ChEBI:CHEBI:15377,

CC Evidence={ECO:0000256|ARBA:ARBA00001746,
CC ECO:0000256|PIRNR:PIRNR017689};
CC -!- COFACTOR:
CC Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC Evidence={ECO:0000256|ARBA:ARBA00001933,
CC ECO:0000256|PIRNR:PIRNR017689, ECO:0000256|PIRSR:PIRSR017689-50};
CC -!- PATHWAY: Aminoacyl-tRNA biosynthesis; selenocysteinyl-tRNA(Sec)
CC biosynthesis; selenocysteinyl-tRNA(Sec) from L-seryl-tRNA(Sec)
CC (archaeal/eukaryal route): step 2/2. {ECO:0000256|ARBA:ARBA00004822,
CC ECO:0000256|PIRNR:PIRNR017689}.
CC -!- SUBUNIT: Homotetramer formed by a catalytic dimer and a non-catalytic
CC dimer serving as a binding platform that orients tRNASec for catalysis.
CC Each tetramer binds the CCA ends of two tRNAs which point to the active
CC sites of the catalytic dimer. {ECO:0000256|ARBA:ARBA00026053}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|PIRNR:PIRNR017689}.
CC -!- SIMILARITY: Belongs to the SepSecS family.
CC {ECO:0000256|ARBA:ARBA00007037, ECO:0000256|PIRNR:PIRNR017689}.
