Enzyme Information
| 2.9.1.2 |
O-phospho-L-seryl-tRNA(Sec):L-selenocysteinyl-tRNA synthase.
based on mapping to UniProt Q9HD40
O-phospho-L-seryl-tRNA(Sec) + selenophosphate + H(2)O = L-selenocysteinyl-tRNA(Sec) + 2 phosphate.
-!- In archaea and eukarya selenocysteine formation is achieved by a two- step process: EC 2.7.1.164 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 Sep-tRNA:Sec-tRNA synthase. -!- Formerly EC 2.9.1.n1.
