CC   -!- FUNCTION: Catalyzes the ATP-dependent conversion of 7-carboxy-7-
CC       deazaguanine (CDG) to 7-cyano-7-deazaguanine (preQ(0)).
CC       {ECO:0000255|HAMAP-Rule:MF_01633}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=7-carboxy-7-deazaguanine + ATP + NH4(+) = 7-cyano-7-
CC         deazaguanine + ADP + H(+) + H2O + phosphate; Xref=Rhea:RHEA:27982,

CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01633};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01633};
CC   -!- PATHWAY: Purine metabolism; 7-cyano-7-deazaguanine biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_01633}.
CC   -!- SIMILARITY: Belongs to the QueC family. {ECO:0000255|HAMAP-
CC       Rule:MF_01633}.
