These changes prevent insulin molecules from clumping together, and thereby improve the manufactured insulin's biological properties.

Certain hormones, such as epinephrine, can increase the levels ofcAMP within cells. Let’s suppose you pretreat cells with or withoutepinephrine and then prepare a cell extract that contains theCREB protein.You then use an electrophoretic mobility shift assay to analyzethe ability of the CREB protein to bind to a DNA fragmentcontaining a cAMP response element (CRE). Describe what theexpected results would be.

The codon change (Gly-12 to Val-12) in human rasH that convertsit to oncogenic rasH has been associated with many types ofcancers. For this reason, researchers would like to develop drugs toinhibit oncogenic rasH. Based on your understanding of the Rasprotein, what types of drugs might you develop? In other words,what would be the structure of the drugs, and how would theyinhibit Ras protein? How would you test the efficacy of the drugs?What might be some side effects?

Jack is applyng to Gate's foundation for a grant to make a high affinity, humanized monoclonal antibody that could neutralize venom, a 7 kDa protein of 62 amino aicds, from cobra snakes. He argues that many people in tropical areas are bitten by the poisonous snakes and may need injection of this life-saving anitbody more than once. His friend has successfully purified the 7kDA venom protein expressed in E. coli in a large quantity and will give him whatever he needs for his project. Assume that he recovers four anti-venom monoclonal antibodies. What is the method he can use to identify the one with the highest affinity to the venom?

. Our immune system makes many different proteins thatprotect us from viral and bacterial infection. Biotechnologycompanies must produce large quantities of these immune proteins for human testing and eventual sale to thepublic. To this end, their scientists engineer bacterial orhuman cell cultures to express these immune proteins.Explain why proteins isolated from bacterial cultures areoften inactive, whereas the same proteins isolated fromhuman cell cultures are active (functional).
Rationalize the following observations.(a) Serine is the amino acid residue that can be replaced with theleast effect on protein structure and function.(b) Replacement of tryptophan causes the greatest effect on protein structure and function.(c) Replacements such as Lys -> Arg and Leu -> Ile usually havevery little effect on protein structure and function.
