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.
面包酵母中的诱导型半乳糖转运系统可促进非代谢性半乳糖类似物d-岩藻糖和l-阿拉伯糖的扩散。这种能力取决于Ga 2基因的活性。在某些菌株中,d-岩藻糖和l-阿拉伯糖也是安慰诱导物。半乳糖途径酶诱导性发生改变的突变体,其半乳糖转运系统的诱导性也会发生平行改变。
