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 ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,

CC Evidence={ECO:0000255|HAMAP-Rule:MF_01633};
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}.
