- 2-aminomuconate + H2O 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.
