Product Name O-phosphoseryl-tRNASec kinase
Example Structure Example Structure of O-phosphoseryl-tRNASec kinase EC#: 2.7.1.164
Synonyms O-phosphoseryl-tRNA kinase, O-phosphoseryl-tRNA(Sec) kinase, O-phosphoseryl-tRNASec kinase, phosphoseryl-tRNASec kinase, phosphoseryl-tRNA[Ser]Sec kinase, PSTK
EC Number 2.7.1.164
CAS Registry Number 91273-83-5
Comments In archaea and eukarya selenocysteine formation is achieved by a two-step process:?O-phosphoseryl-tRNASec?kinase (PSTK) phosphorylates the endogenous?L-seryl-tRNASec?to?O-phospho-L-seryl-tRNASec, and then this misacylated amino acid-tRNA species is converted to?L-selenocysteinyl-tRNASec?by EC?2.9.1.2?(Sep-tRNA:Sec-tRNA synthase).
Cofactor
History
Reactions Atp + L-seryl-tRNA(Sec) = adp + O-phospho-L-seryl-tRNA(Sec).
