The Lac operon | Regulation of gene expression

The lac operon (lactose operon) is an operon required for the transport and metabolism of lactose in Escherichia coli and many other enteric bacteria. The lac operon allows for the effective digestion of lactose when glucose is not available through the activity of beta-galactosidase. Gene regulation (regulation of gene expression) of the lac operon was the first genetic regulatory mechanism to be understood clearly, so it has become a foremost example of prokaryotic gene regulation. This lactose metabolism system was used by François Jacob and Jacques Monod to determine how a biological cell knows which enzyme to synthesize. Their work on the lac operon won them the Nobel Prize in Physiology in 1965.

Great video, only issue is lactose doesn’t bind to the repressor, allolactose does. B galactosidase converts some lactose into allolactose, hence binding to the allosteric site of the repressor.

After months rereading this topic, I finally got it! Thank you so much... Such a great explanation!

[nicolassardella]

Great explanation- very informative and to the point while covering all the important details. Thanks!

Great video, but one thing to correct. It's allolactose that binds the repressor. (It's a side product of splitted Lactose).

The best explanation. short but straight to the point and very simplified term. Thank you
