In enzymology, a 6-aminohexanoate-dimer hydrolase (EC 3.5.1.46) is an enzyme that catalyzes the chemical reaction

N-(6-aminohexanoyl)-6-aminohexanoate + H₂O $\rightleftharpoons$ 2 6-aminohexanoate

Thus, the two substrates of this enzyme are N-(6-aminohexanoyl)-6-aminohexanoate and H₂O, whereas its product is 6-aminohexanoate.

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 N-(6-aminohexanoyl)-6-aminohexanoate amidohydrolase. This enzyme is also called 6-aminohexanoic acid oligomer hydrolase.

Structural studies

As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes 1WYB, 1WYC, and 2DCF.
