Characterization of SotA and SotB, two Erwinia chrysanthemi proteins which modify isopropyl-beta-D-thiogalactopyranoside and lactose induction of the Escherichia coli lac promoter.

Abstract excerpt

The expression, in Escherichia coli, of variants of the Erwinia chrysanthemi secretion genes outB and outS under the Ptac promoter is toxic to the cells. During attempts to clone E. chrysanthemi genes able to suppress this toxicity, I identified two genes, sotA and sotB, whose products are able to reduce the isopropyl-beta-D-thiogalactopyranoside (IPTG) induction of the E. coli lac promoter. SotA and SotB belong...
