Chain A,B   (PSTK_METJA | Q58933)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0016301    kinase activity    Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
    GO:0000166    nucleotide binding    Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
    GO:0016773    phosphotransferase activity, alcohol group as acceptor    Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to an alcohol group (acceptor).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0016310    phosphorylation    The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
    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.
