Enzyme Information

6.1.1.10
Methionine--tRNA ligase.
based on mapping to UniProt P00959
ATP + L-methionine + tRNA(Met) = AMP + diphosphate + L-methionyl- tRNA(Met).
-!- In those organisms producing N-formylmethionyl-tRNA(fMet) for translation initiation, this enzyme also recognizes the initiator tRNA(fMet) and catalyzes the formation of L-methionyl-tRNA(fMet), the substrate for EC 2.1.2.9.
