Answer #1

Ferric upake regulation protein (fur )regulates expression of several outer membranes protein including the iron transport opron.

Since it is not constantly expressed ,hence it is NOT CONSTITUTIVE PROTEIN.

It is not involved in binding site other than active site ,hence it is not ALLOSTERIC PROTEIN.

It is NOT A REPRESSOR PROTIEN.

HENCE,ONLY ONE STATEMENT IS TRUE.

    As part of the regulatory response to decreasing oxygen levels, the FNR protein of E. coli upregulates expression of the Fumarate and Nitrate Reductases, as well as the pyruvate formate-lyase enzyme. What is the function of the pyruvate formate-lyase enzyme, and why would it be up-regulated under anaerobic conditions?

    See Hint In E. coli, eight enzymatic steps are involved in the biosynthesis of arginine from glutamate. The synthesis of the required enzymesis subject to control by the ArgD protein, which, on its own, binds weakly to a regulatory sequence just downstream of the promoter regions for these genes. Upon the addition of excess arginine to the growth medium, the respective mRNA molecules are no longer produced. What is the likely role of arginine in the control of these genes?...

    Consider an E. coli strain carrying a mutation in crp (encoding the catabolite activator protein) that prevents CAP from binding CAMP. Predict whether the repressor and the activator is active (able to bind to DNA) or inactive (unable to bind to DNA), and the level of transcription in the following scenarios. Options for transcription levels include high, medium, leaky and off. a. When lactose is present but glucose is not, the repressor is and the activator is leading to levels...
