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-
