Spontaneous mutations affecting transcriptional regulation by protocatechuate in Acinetobacter.

FEMS microbiology letters - 10 Jul 2001

D'Argenio D A, Segura A, Bünz P V, Ornston L N

Abstract excerpt

Positive selection yields Acinetobacter strains with a spontaneous mutation blocking catabolism of protocatechuate. For this study, the growth temperature during selection was lowered to 22 degrees C: growth at 37 degrees C was found to mask the role of the protocatechuate-responsive transcriptional regulator PcaU. The resulting mutants included those with amino acid substitutions useful for understanding PcaU...
