WebL' opéron lactose, ou opéron lac est un opéron nécessaire au transport et au métabolisme du lactose chez Escherichia coli, ainsi que d'autres bactéries de la flore intestinale. L'opéron lactose est composé de trois gènes structurels : lacZ, lacY et lacA. Il est régulé par plusieurs facteurs, notamment la disponibilité en glucose et ... WebWe have used the lactose system in Escherichia coli to quantify the cost of growth on glycerol in the presence of isopropyl-β-D-thiogalactopyranoside (IPTG), an inducer of the lactose system. The effect of the concentration of the carbon source, glycerol, and the inducer of Lac enzymes, IPTG, is studied.
