CC   -!- FUNCTION: Catalyzes the NADPH-dependent reduction of 7-cyano-7-
CC       deazaguanine (preQ0) to 7-aminomethyl-7-deazaguanine (preQ1) (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: 7-aminomethyl-7-carbaguanine + 2 NADP(+) = 7-
CC       cyano-7-carbaguanine + 2 NADPH.
CC   -!- PATHWAY: tRNA modification; queuosine-tRNA biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (Probable).
CC   -!- SIMILARITY: Belongs to the GTP cyclohydrolase I family. QueF type
CC       2 subfamily.
