Catalytic activity

7-aminomethyl-7-carbaguanine + 2 NADP+ = 7-cyano-7-carbaguanine + 2 NADPH. HAMAP-Rule MF_00817

Pathway

tRNA modification; tRNA-queuosine biosynthesis. HAMAP-Rule MF_00817

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the GTP cyclohydrolase I family. QueF type 2 subfamily.
