Leucyltransferase

In enzymology, a leucyltransferase is an enzyme that catalyzes the chemical reaction


 * L-leucyl-tRNA + protein $$\rightleftharpoons$$ tRNA + L-leucyl-protein

Thus, the two substrates of this enzyme are L-leucyl-tRNA and protein, whereas its two products are tRNA and L-leucyl-protein.

This enzyme belongs to the family of transferases, specifically the aminoacyltransferases. The systematic name of this enzyme class is L-leucyl-tRNA:protein leucyltransferase. Other names in common use include leucyl, phenylalanine-tRNA-protein transferase, leucyl-phenylalanine-transfer ribonucleate-protein, aminoacyltransferase, and leucyl-phenylalanine-transfer ribonucleate-protein transferase.

Structural studies
As of late 2007, three structures have been solved for this class of enzymes, with PDB accession codes, , and.
