Enzyme Information
| 6.1.1.11 |
Serine--tRNA ligase.
based on mapping to UniProt P49591
(1) ATP + L-serine + tRNA(Ser) = AMP + diphosphate + L-seryl-tRNA(Ser). (2) ATP + L-serine + tRNA(Sec) = AMP + diphosphate + L-seryl-tRNA(Sec).
-!- This enzyme also recognizes tRNA(Sec), the special tRNA for selenocysteine, and catalyzes the formation of L-seryl-tRNA(Sec), the substrate for EC 2.9.1.1.
