In enzymology, 2-aminomuconate deaminase (EC 3.5.99.5) (also known as amnd) is an enzyme that catalyzes the chemical reaction
- 2-aminomuconate + H2O [math]\displaystyle{ \rightleftharpoons }[/math] 4-oxalocrotonate + NH3
Thus, the two substrates of this enzyme are 2-aminomuconate and H2O, whereas its two products are 4-oxalocrotonate and NH3.
This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in compounds that have not been otherwise categorized within EC number 3.5. The systematic name of this enzyme class is 2-aminomuconate aminohydrolase. This enzyme participates in tryptophan metabolism.
