molecular function
    GO:0004125    L-seryl-tRNASec selenium transferase activity    Catalysis of the reaction: L-seryl-tRNA(Sec) + selenophosphate = L-selenocysteinyl-tRNA(Sec) + H2O + phosphate.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
biological process
    GO:0097056    selenocysteinyl-tRNA(Sec) biosynthetic process    The chemical reactions and pathways resulting in the formation of selenocysteinyl-tRNA(Sec). This process occurs through the following steps: a unique serine-tRNA with a UGA recognizing anticodon is first aminoacylated with serine; this is then phosphorylated by phosphoseryl-tRNA[Ser]Sec kinase; lastly, selenium is swapped for the phosphate on the serine.
