In enzymology, a sepiapterin deaminase (EC 3.5.4.24) is an enzyme that catalyzes the chemical reaction
- sepiapterin + H2O [math]\displaystyle{ \rightleftharpoons }[/math] xanthopterin-B2 + NH3
Thus, the two substrates of this enzyme are sepiapterin and H2O whereas its two products are xanthopterin-B2 and NH3.
This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amidines. The systematic name of this enzyme class is sepiapterin aminohydrolase.
