The non-inducible nature of super-repressors of the gal operon in Escherichia coli.
Journal of Molecular Biology, 1995We isolated and characterized mutant repressors (GalR) of the gal operon in Escherichia coli. These repressors (super-repressors), called GalRs, have a non-inducible phenotype. Repression of the gal operon by super-repressors cannot be lifted by inducer.

Journal of Molecular Biology, 1968 Two fractions corresponding to the separated complementary DNA strands, W(= l ) and C(= r ), were obtained by CsCl density-gradient centrifugation of a complex between poly (I,G) or poly (U,G) and denatured DNA isolated from a defective coliphage, λdg D-J , containing the entire galactose ( gal ) operon, which includes genes e (epimerase), t ...

The infection of E. coli cells with different lambdoïd prophages triggers a stimulation of galactokinase synthesis when cells are grown in a medium giving rise to a mild catabolite repression (tryptone broth) with an inducer of the gal operon (fucose). These results show that during phage infection (or induction) some factor acting in trans is produced

A 500-MHz 1H-NMR study on a double-stranded non-self-complementary DNA undecamer comprising a portion of the specific target site for the cyclic AMP receptor protein in the gal operon is presented.

Construction and properties of hybrid plasmids carrying the E. coli gal operon
Gene, 1979A family of hybrid plasmids carrying the entire gal operon of E. coli and designated pgal was constructed in vitro. In the case of pgal 1 (mol. wt. 16.4 Md), a fragment cut by Bam HI endonuclease from lambda gal phage DNA (lambda D-J-gal-att-int) was joined to pMB9 and cloned in the gal-strain of E.

The Escherichia coli galactose operon contains an unusual array of closely spaced binding sites for proteins governing the expression from the two physically overlapping gal promoters. Based on studies of two gal promoter-up mutants we have previously suggested RNA-polymerase-induced DNA bending of gal promoter DNA.
