RL   Submitted (AUG-2007) to the EMBL/GenBank/DDBJ databases.
CC   -!- FUNCTION: Repressor of rcnA expression. Acts by binding specifically to
CC       the rcnA promoter in the absence of nickel and cobalt. In the presence
CC       of one of these metals, it has a weaker affinity for rcnA promoter (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the FrmR/RcnR family. {ECO:0000305}.
