O-phosphoseryl-tRNASec kinase (EC 2.7.1.164, PSTK, phosphoseryl-tRNA[Ser]Sec kinase, phosphoseryl-tRNASec kinase) is an enzyme with systematic name ATP:L-seryl-tRNASec O-phosphotransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- ATP + L-seryl-tRNASec [math]\displaystyle{ \rightleftharpoons }[/math] ADP + O-phospho-L-seryl-tRNASec
In archaea and eukarya selenocysteine formation is achieved by a two-step process.
