In the context of the E. coli fepCDG operon, the term "one-component" refers to
A. Fe.
B. Fur.
C. the fur box.
D. the fepCDG operon promoter.
Homework Answers
Answer:- (B). Fur.
Fep C, G, D, IM pump in an operon, fepCDG, are on one mRNA. FepCDG is regulated environmentally, so that the pump is expressed only when Fe is minimal in the environment. The fur box is the handler for this operon. Fur box partially overlaps fep supporting sequence.In the fep promoter / operator, the fur binds to the fur box. This will block transcription. Fur binds to the Operator and Fe. Fe causes binding of the fur inhibiting the production of pumps that inhibits the transport of fe. The synthesis of Siderophore also has a fur-box. The manufacture of pumps is synchronized.

The FepC, D and G are proteins of E. coli are required to transport Fe-siderophore complexes from the periplasm across the cytoplasmic membrane into the cytoplasm. In order to first transport these complexes from the environment into the periplasm, the outer membrane protein FepA is required. Expression of the fepA gene is regulated in the same way as expression of the genes in the fepCDG operon. Given this information, which one of the following statements is correct? A. In the...

Methionine is an amino acid made by E coli. The met (methionine) operon in E. coli responds to a repressor protein which itself is: a. encoded by the operon b. turned off when bound to methionine c. turned on when bound to methionine d. unresponsive to any product of the methionine biosynthetic pathway e. turned on when bound to tryptophan

In E coli the lac operon will express enzymes for the digestion of (Glucose/Lactose) when it is present, but if both the sugar mentioned before and (Glucose/ Lactose) are present the lac operon is repressed, resulting in the (Glucose/ Lactose) being used first. If there are high levels of cAMP, this means (Glucose/Lactose) levels are low, this results in a (Represser/Promoter) being activated and (Decreasing/Increasing) transcription of the lac operon.

26. The lac operon in E. coli consists of genes that code for enzymes necessary for the breakdown of lactose. When lactose is absent, the operon is inactive because a repressor protein binds to a specific site in the lac operon. When lactose is present, lactose molecules bind to the repressor protein, causing the repressor protein to dissociate from the binding site. In the absence of glucose (a preferred energy source for bacteria), the protein CAP binds to a regulatory...
