Abstract excerpt
The LysR protein PcaQ regulates the expression of genes encoding products relevant to the degradation of the aromatic acid protocatechuate (3,4-dihydroxybenzoate), and we have previously defined a PcaQ DNA-binding site located upstream of the target pcaDCHGB operon in Sinorhizobium meliloti. In this work, we show that PcaQ also regulates the expression of the S. meliloti...
