O-phosphoseryl-tRNASec kinase

FieldValue
NameO-phosphoseryl-tRNASec kinase
EC_number2.7.1.164
CAS_number91273-83-5

O-phosphoseryl-tRNASec kinase (, PSTK, phosphoseryl-tRNA[Ser]Sec kinase, phosphoseryl-tRNASec kinase) is an enzyme with systematic name ATP:L-seryl-tRNASec O-phosphotransferase. This enzyme catalyses the following chemical reaction

: ATP + L-seryl-tRNASec \rightleftharpoons ADP + O-phospho-L-seryl-tRNASec

In archaea and eukarya selenocysteine formation is achieved by a two-step process.
