In enzymology a preQ1 synthase (EC 1.7.1.13) is an enzyme that catalyzes the chemical reaction7-aminomethyl-7-carbaguanine + 2 NADP+ 7-cyano-7-carbaguanine + 2 NADPH + 2 H+Thus the two substrates of this enzyme are 7-aminomethyl-7-carbaguanine and NADP+ whereas its 3 products are 7-cyano-7-carbaguanine NADPH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on other nitrogenous compounds as donors with NAD+ or NADP+ as acceptor.
