IntEnz Enzyme Nomenclature
EC 6.1.1.10

Names

Accepted name:
methionine—tRNA ligase
Other names:
MetRS
methionine translase
methionyl-tRNA synthetase
methionyl-transfer RNA synthetase
methionyl-transfer ribonucleate synthetase
methionyl-transfer ribonucleic acid synthetase
Systematic name:
L-methionine:tRNAMet ligase (AMP-forming)

Reaction

Comments:

In those organisms producing N-formylmethionyl-tRNAfMet for translation initiation, this enzyme also recognizes the initiator tRNAfMet and catalyses the formation of L-methionyl-tRNAfMet, the substrate for EC 2.1.2.9, methionyl—tRNA formyltransferase.
