Question

pt 0l the RZyme), thus either activating or inactivating the protein. The same holds true for transcription factors. They themselves can be turned ON or OFF by the presence of certain small compounds. 5. In the figure below, the blue protein needs to be bound to the small compound before it can bind to the DNA. Therefore, it has two "sites", an allosteric site that binds to the small compound and a DNA binding domain that binds to the DNA. A. Label the allosteric site on the transcription factor B. Label the DNA binding domain on the transcription factor.

Explanation / Answer

Hello,

Since you have answered A,B and C by yourself am assuming that you need help with D and E.

D- Since binding of small compound is increasing the binding of transcription factor to DNA, if transcription factor was an activator then the small compound would have helped to enhance the rate of gene expression.

E- Similarly if transcription factor was a repressor then the small compound would have helped to downregulate the rate of gene expression.
