In enzymology, an acetylornithine deacetylase (EC 3.5.1.16) is an enzyme that catalyzes the chemical reaction
- N2-acetyl-L-ornithine + H2O acetate + L-ornithine
Thus, the two substrates of this enzyme are N2-acetyl-L-ornithine and H2O, whereas its two products are acetate and L-ornithine.
This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N2-acetyl-L-ornithine amidohydrolase. Other names in common use include acetylornithinase, N-acetylornithinase, and 2-N-acetyl-L-ornithine amidohydrolase. This enzyme participates in urea cycle and metabolism of amino groups.
Structural studies
[edit]As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 2F7V and 2F8H.
