Mode of action of AraR, the key regulator of L-arabinose metabolism in Bacillus subtilis.

Abstract

The AraR protein is a negative regulator involved in L-arabinose-inducible expression of the Bacillus subtilis araABDLMNPQ-abfA metabolic operon and of the araE/araR genes that are organized as a divergent transcriptional unit. The two ara gene clusters are found at different positions in the bacterial chromosome. AraR was overproduced in Escherichia coli… (More)
