PreQ(1) synthase.
based on mapping to UniProt Q9KTK0
7-aminomethyl-7-carbaguanine + 2 NADP(+) = 7-cyano-7-carbaguanine + 2 NADPH.
-!- The reaction occurs in the reverse direction. -!- This enzyme catalyzes one of the early steps in the synthesis of queosine (Q-tRNA), and is followed by the action of EC 2.4.2.29. -!- Queosine is found in the wobble position of tRNA(GUN) in eukaryotes and bacteria and is thought to be involved in translational modulation.
