7-cyano-7-deazaguanine synthase (EC 6.3.4.20, preQ0 synthase, 7-cyano-7-carbaguanine synthase, queC (gene)) is an enzyme with systematic name 7-carboxy-7-carbaguanine:ammonia ligase (ADP-forming). This enzyme catalyses the following chemical reaction

7-carboxy-7-carbaguanine + NH₃ + ATP ⇌ 7-cyano-7-carbaguanine + ADP + phosphate + H₂O

This enzyme binds Zn²⁺.
