Isorepressor of the gal regulon in Escherichia coli.

Journal of molecular biology - 5 Jul 1992

Weickert M J, Adhya S

Abstract excerpt

Inducible overexpression of the Escherichia coli gal operon in the absence of the Gal repressor is known as ultrainduction. The requirement of induction can be eliminated by mutation of a new locus, galS, resulting in constitutive and ultrainduced levels of gal expression. Characterization of the galS gene and its product has revealed an isorepressor of the gal regulon. The Gal isorepressor is a protein of 346...
