Regulation of gene expression by repressor localization: biochemical evidence that membrane and DNA binding by the PutA protein are mutually exclusive.

Journal of bacteriology - 1 Apr 1997

Muro-Pastor A M, Ostrovsky P, Maloy S

Abstract excerpt

The PutA protein from Salmonella typhimurium is a bifunctional enzyme that catalyzes the oxidation of proline to glutamate, a reaction that is coupled to the transfer of electrons to the electron transport chain in the cytoplasmic membrane. The PutA protein is also a transcriptional repressor that regulates the expression of the put operon in response to the availability of proline. Despite extensive genetic and...
