FUNCTIONCatalyzes the NADPH-dependent reduction of 7-cyano-7- deazaguanine (preQ0) to 7-aminomethyl-7-deazaguanine (preQ1).
CATALYTIC ACTIVITY Reaction=7-aminomethyl-7-carbaguanine + 2 NADP(+) = 7-cyano-7- deazaguanine + 3 H(+) + 2 NADPH; Xref=Rhea:RHEA:13409, ChEBI:CHEBI:15378, ChEBI:CHEBI:45075, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, ChEBI:CHEBI:58703; EC=;
PATHWAYtRNA modification; tRNA-queuosine biosynthesis.
SIMILARITYBelongs to the GTP cyclohydrolase I family. QueF type 1 subfamily.
