BRITE hierarchy
Sysname
ATP:L-seryl-tRNASec O-phosphotransferase
Reaction(IUBMB)
ATP + L-seryl-tRNASec = ADP + O-phospho-L-seryl-tRNASec [RN:R08223]
Reaction(KEGG)
Substrate
ATP [CPD:C00002];
L-seryl-tRNA(Sec) [CPD:C06481]
Product
ADP [CPD:C00008];
O-phospho-L-seryl-tRNASec
Comment
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).
