Sepiapterin deaminase explained

sepiapterin deaminase
Ec Number:3.5.4.24
Cas Number:62213-22-3
Go Code:0050279

In enzymology, a sepiapterin deaminase is an enzyme that catalyzes the chemical reaction

sepiapterin + H2O

\rightleftharpoons

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.
