In enzymology a 5-amino-6-(5-phosphoribosylamino)uracil reductase (EC 1.1.1.193) is an enzyme that catalyzes the chemical reaction5-amino-6-(5-phosphoribitylamino)uracil + NADP+ 5-amino-6-(5-phosphoribosylamino)uracil + NADPH + H+Thus the two substrates of this enzyme are 5-amino-6-(5-phosphoribitylamino)uracil and NADP+ whereas its 3 products are 5-amino-6-(5-phosphoribosylamino)uracil NADPH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.
