Catabolite repression and induction of the Mg(2+)-citrate transporter CitM of Bacillus subtilis.

abstract：:The gal3 mutation of Saccharomyces, which is associated with an impairment in the utilization of galactose, has been shown to be pleiotropic, causing similar impairments in the utilization of melibiose and maltose. Milibiose utilization and alpha-galactosidase production are directly controlled by the galactose regula...
