Comments

FUNCTION: Catalyzes the NADPH-dependent reduction of 7-cyano-7-deazaguanine (preQ0) to 7-aminomethyl-7-deazaguanine (preQ1) (By similarity).
CATALYTIC ACTIVITY: 7-aminomethyl-7-carbaguanine + 2 NADP⁺ = 7-cyano-7-carbaguanine + 2 NADPH.
PATHWAY: tRNA modification; queuosine-tRNA biosynthesis .
SUBCELLULAR LOCATION: Cytoplasm (Probable).
SIMILARITY: Belongs to the GTP cyclohydrolase I family. QueF type 1 subfamily.
