CC   -!- FUNCTION: Transcriptional repressor for the nicAB operon, encoding the
CC       upper aerobic nicotinate degradation pathway. Acts under non-induced
CC       conditions: repression of the nicAB operon becomes alleviated in
CC       presence of either nicotinate or 6-hydroxynicotinate (6HNA).
CC       {ECO:0000269|PubMed:21450002}.
CC   -!- PATHWAY: Cofactor degradation; nicotinate degradation [regulation].
CC       {ECO:0000269|PubMed:21450002}.
CC   -!- INDUCTION: Expressed at a basal level under non-inducing conditions,
CC       but expression increases when the cells are grown in nicotinate as sole
CC       carbon source. {ECO:0000269|PubMed:21450002}.
CC   -!- DISRUPTION PHENOTYPE: Growth in nicotinate or 6HNA is similar to that
CC       of the wild-type strain. Mutant strain shows constitutive levels of
CC       nicotinate hydroxylase activity, and these levels are similar to the
CC       induced levels detected in the wild-type strain grown in nicotinate. On
CC       the contrary, the NicX activity shows the same induction profile than
CC       that observed in the parental strain. {ECO:0000269|PubMed:21450002}.
