Question

LuxR is allosterically regulated by the inducer molecule secreted by V. fischeri. What does it mean that LuxR is allosterically regulated?

Accepted Answer

Welcome back. Let's look at our next problem during like Alexis, phosphate fructose canes transforms A. D. P into a teepee. If there's too much a teepee produced the A. T. P negatively inhibits the P. F. K. Halting A TP production 80 p in this case acts as a blank. Um All four of our answer choices when we look at them. Um The first part of the phrases Alice Terek hysteric regulation involves things binding to something other than the active site. Um But we don't have to choose between that. So eight Ep is acting in analyst eric fashion but we have the choice of an activator inhibitor repressor and inducer. Well repressors and activators, our regulatory proteins that bind to the DNA to promote or inhibit transcription and A. T. P. Is not a protein. It's a small molecule. So therefore Choice A. And Choice C. Are not are correct answers because they refer to regulatory proteins that bind directly to D. N. A. So we have left inhibitors and inducers um uh inhibitors and inducers are small molecules that bind to repressors and activators. But obviously since A. T. P. Is halting its own production that means it's acting as an inhibitor, not an inducer. Since an inducer would be promoting the production of it. So our correct answer is choice be Alice Terek inhibitor. So during like Alice Foster transforms a d. P into a teepee, there's too much a teepee produced the A. T. P negatively inhibits the P. F. K. Halting A Tv production 80 P. I. In this case acts as N. B. Choice be Alice terek inhibitor. Uh There's a small molecule binding to the p f k protein acting to halt its own production. See you in the next video.
