ATP + L-seryl-tRNASec PSTK distinguishes tRNASec from tRNASer. Unlike eukaryotic PSTK, the archaeal enzyme recognizes the acceptor stem rather than the length and secondary structure of the D-stem. The seryl moiety of L-seryl-tRNASec is not required for enzyme recognition, as PSTK efficiently phosphorylates L-threonyl-tRNASec Methanocaldococcus jannaschii O-phospho-L-seryl-tRNASec + ADP
