Other names:
leucyl, phenylalanine-tRNA-protein transferase
leucyl-phenylalanine-transfer ribonucleate-protein aminoacyltransferase
leucyl-phenylalanine-transfer ribonucleate-protein transferase
leucyl/phenylalanyl-tRNA--protein transferase
leucyl-tRNA--protein transferase
L/F transferase
L-leucyl-tRNA:protein leucyltransferase
Systematic name:
L-leucyl-tRNALeu:protein leucyltransferase




Also transfers phenylalanyl groups. Requires a univalent cation. Peptides and proteins containing an N-terminal arginine, lysine or histidine residue can act as acceptors.
