Enzymes and Genes:
|Escherichia coli K-12 substr. MG1655 :||leucyl, phenylalanyl-tRNA-protein transferase
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: leucyltransferase
Enzyme Commission Synonyms: leucyl, phenylalanine-tRNA-protein transferase, leucyl-phenylalanine-transfer ribonucleate-protein aminoacyltransferase, leucyl-phenylalanine-transfer ribonucleate-protein transferase, L-leucyl-tRNA:protein leucyltransferase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -1.1312561 [Latendresse13]
Enzyme Commission Summary:
Also transfers phenylalanyl groups. Requires a univalent cation. Peptides and proteins containing an N-terminal arginine, lysine or histidine residue can act as acceptors.
