The LysR-type PcaQ protein regulates expression of a protocatechuate-inducible ABC-type transport system in Sinorhizobium meliloti
Abstract
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 smb20568-smb20787-smb20786-smb20785-smb20784 gene cluster, which is …
