CC -!- FUNCTION: Negatively regulates transcription of bacterial
CC ribonucleotide reductase nrd genes and operons by binding to NrdR-
CC boxes. {ECO:0000256|HAMAP-Rule:MF_00440}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00440};
CC Note=Binds 1 zinc ion. {ECO:0000256|HAMAP-Rule:MF_00440};
CC -!- SIMILARITY: Belongs to the NrdR family. {ECO:0000256|HAMAP-
CC Rule:MF_00440}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
