The presence of glucose represses the lac operon even if an inducer (lactose) is present. View chapterExplore book Computer Methods, Part C Necmettin Yildirim, Caner Kazanci, in Methods in Enzymology, 2011 4 An Example: Lactose Operon in E. coli We use the lactose operon (the lac operon)...
(iv) In lac operon, the repressor is synthesised only at the time when the level of metabolite is in excess. Find out the correct statements? View Solution A considerable amount of lactose is added to the growth medium of E.coli. How is the lac operon switched on in the bacteria.? Men...

This chapter highlights lactose (lac) permease transport system of Escherichia coli ( E.coli ). The accumulation of β -galactosides against a concentration gradient in E.coli is carried out by lac permease, which is a hydrophobic polytopic cytoplasmic membrane protein that catalyzes the coupled tr...
The lac operon encodes for the genes needed to utilize lactose as an energy source. The lac operon contains an operator, promoter, and structural genes. These genes are transcribed together and are under the control of the catabolite activator protein (C

1 Such a grouping of regulating and structural genes is termed an operon. In 1961 Jacob and Monod proposed a mechanism for the regulation of the activity of this operon. At this time no promoter region had been defined although no reasonable person would have denied that there must be ...
