EC Number: 18.104.22.168
In Pathway: tRNA charging
The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the direction in which it was curated.
Most BioCyc compounds have been protonated to a reference pH value of 7.3. Please see the PGDB Concepts Guide for more information.
Mass balance status: The left side is missing: Elongation-tRNAMet: 1 . The right side is missing: MET-tRNAs: 1
Enzyme Commission Primary Name: methionine—tRNA ligase
Enzyme Commission Synonyms: methionyl-tRNA synthetase, methionyl-transfer ribonucleic acid synthetase, methionyl-transfer ribonucleate synthetase, methionyl-transfer RNA synthetase, methionine translase, MetRS
Enzyme Commission Summary:
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 22.214.171.124, methionyl-tRNA formyltransferase.
