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}.
