O-phosphoseryl-tRNA(Sec) kinase.
based on mapping to UniProt Q58933
ATP + L-seryl-tRNA(Sec) = ADP + O-phospho-L-seryl-tRNA(Sec).
-!- In archaea and eukarya selenocysteine formation is achieved by a two- step process: O-phosphoseryl-tRNA(Sec) kinase (PSTK) phosphorylates the endogenous L-seryl-tRNA(Sec) to O-phospho-L-seryl-tRNA(Sec), and then this misacylated amino acid-tRNA species is converted to L-selenocysteinyl-tRNA(Sec) by EC 2.9.1.2. -!- Formerly EC 2.7.1.n3.
