CC Name=Ni(2+); Xref=ChEBI:CHEBI:49786; Evidence={ECO:0000250};
CC Note=Binds 1 nickel ion per subunit. {ECO:0000250};
CC -!- SUBUNIT: Homotetramer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the transcriptional regulatory CopG/NikR family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAL53728.1; Type=Erroneous initiation; Evidence={ECO:0000305};
