Bacillus subtilis gnt repressor mutants that diminish gluconate-binding ability
Abstract
The Bacillus subtilis gnt operon is negatively regulated by GntR, which is antagonized by gluconate. Three GntR mutants with diminished gluconate-binding ability were obtained. Two were missense mutants (Met-209 to Ile and Ser-230 to Leu), whereas the third had a deletion of the C-terminal 23 amino acids. The mutant GntR proteins were unable to become properly detached from the gnt operator even in the presence of gluconate.
