CC   -!- FUNCTION: Transcriptional activator of anaerobic gene expression.
CC       Regulates the expression of the components of the hydrogen cyanide
CC       synthase (HcnABC) in a positive manner (PubMed:10570200). May also act
CC       as an iron sensor. {ECO:0000269|PubMed:11021918,
CC       ECO:0000269|PubMed:9620970, ECO:0000305|PubMed:10570200}.
CC   -!- INDUCTION: Up-regulated by Fe(3+) levels in oxygen-limiting conditions.
CC       {ECO:0000269|PubMed:11021918, ECO:0000269|PubMed:9620970}.
CC   -!- DISRUPTION PHENOTYPE: Nearly complete loss of expression of hcnA
CC       (PubMed:10570200). {ECO:0000269|PubMed:10570200}.
CC   -!- MISCELLANEOUS: Possesses 4 cysteines which may bind a metal ion
CC       (possibly iron). {ECO:0000250|UniProtKB:P23926}.
