Accepted name: serine—tRNA ligase
Reaction: ATP + L-serine + tRNASer = AMP + diphosphate + L-seryl-tRNASer
Other name(s): seryl-tRNA synthetase; SerRS; seryl-transfer ribonucleate synthetase; seryl-transfer RNA synthetase; seryl-transfer ribonucleic acid synthetase; serine translase
Systematic name: L-serine:tRNASer ligase (AMP-forming)
Comments: This enzyme also recognizes tRNASec, the special tRNA for selenocysteine, and catalyses the formation of L-seryl-tRNASec, the substrate for EC, L-seryl-tRNASec selenium transferase.
