EC 2.3.2.6

Accepted name: leucyltransferase

Reaction: L-leucyl-tRNALeu + protein = tRNALeu + L-leucyl-[protein]

Other name(s): leucyl, phenylalanine-tRNA-protein transferase; leucyl-phenylalanine-transfer ribonucleate-protein aminoacyltransferase; leucyl-phenylalanine-transfer ribonucleate-protein transferase; L-leucyl-tRNA:protein leucyltransferase

Systematic name: L-leucyl-tRNALeu:protein leucyltransferase

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