Comments
FUNCTION: Catalyzes the ATP-dependent conversion of 7-carboxy-7-deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)) (By similarity).
CATALYTIC ACTIVITY: 7-carboxy-7-carbaguanine + NH(3) + ATP = 7-cyano-7-carbaguanine + ADP + phosphate + H(2)O.

case <FTGroup:1>
COFACTOR: Binds 1 zinc ion per subunit (By similarity).
end case

PATHWAY: Purine metabolism; 7-cyano-7-deazaguanine biosynthesis.

case <OC:Firmicutes>
SUBUNIT: Homodimer (By similarity).
end case

SIMILARITY: Belongs to the QueC family.
