Diaminohydroxyphosphoribosylaminopyrimidine deaminase
In enzymology, a diaminohydroxyphosphoribosylaminopyrimidine deaminase (EC3.5.4.26) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are 2,5-diamino-6-hydroxy-4-(5-phosphoribosylamino)pyrimidine and H2O, whereas its two products are 5-amino-6-(5-phosphoribosylamino)uracil and NH3.
