Abstract:
:The inducible galactose transport system in bakers' yeast carries out the facilitated diffusion of the nonmetabolized galactose analogues d-fucose and l-arabinose. This capacity depends on the activity of the Ga 2 gene. In some strains, d-fucose and l-arabinose are also gratuitous inducers. Mutants in which the inducibility of the galactose pathway enzymes is altered show a parallel alteration of the inducibility of the galactose transport system.
