O-phospho-L-seryl-tRNASec:L-selenocysteinyl-tRNA synthase (EC 2.9.1.2, MMPSepSecS, SepSecS, SLA/LP, O-phosphoseryl-tRNA:selenocysteinyl-tRNA synthase, O-phospho-L-seryl-tRNA:L-selenocysteinyl-tRNA synthase) is an enzyme with systematic name selenophosphate:O-phospho-L-seryl-tRNASec selenium transferase.[1][2][3][4] This enzyme catalyses the following chemical reaction
- O-phospho-L-seryl-tRNASec + selenophosphate ⇌ L-selenocysteinyl-tRNASec + phosphate
This enzyme is pyridoxal-phosphate protein.
