Cyclic AMP receptor protein and TyrR are required for acid pH and anaerobic induction of hyaB and aniC in Salmonella typhimurium

K R Park et al. J Bacteriol. 1999 Jan.

Abstract

Two acid-inducible genes, aniC and aciK, that require anaerobiosis and tyrosine for expression were identified as orf326a encoding a potential amino acid/polyamine antiporter and hyaB encoding hydrogenase I, respectively. Cyclic AMP (cAMP) receptor protein, cAMP, and TyrR, regulator of aromatic amino acid metabolism, were strong positive regulators of both genes.
