EC Number: 126.96.36.199
In Pathway: tRNA charging
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: methionine—tRNA ligase
Enzyme Commission Synonyms: methionyl-tRNA synθse, methionyl-transfer ribonucleic acid synθse, methionyl-transfer ribonucleate synθse, methionyl-transfer RNA synθse, 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 188.8.131.52, methionyl-tRNA formyltransferase.
