In enzymology, a glutamate N-acetyltransferase (EC 2.3.1.35) is an enzyme that catalyzes the chemical reaction

N₂-acetyl-L-ornithine + L-glutamate

\rightleftharpoons

L-ornithine + N-acetyl-L-glutamate

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is N2-acetyl-L-ornithine:L-glutamate N-acetyltransferase. This enzyme participates in the urea cycle and metabolism of amino groups.

Structural studies

As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1VRA, 1VZ6, 1VZ7, and 1VZ8.
