Control of the receptor for galactose taxis in Salmonella typhimurium
Abstract
The chemotactic response to galactose in wild-type Salmonella typhimurium is not inducible by galactose, but is inducible by fucose, a non-metabolizable analog. In a galactokinase mutant, however, the galactose receptor is inducible by galactose. These data indicate that the concentration of free galactose in the cell controls the levels of the galactose receptor. The intensities of the chemotactic responses were found to vary in proportion to …
