Question: A decapeptide composed of ser, ala, IIe. his, trp, phe was treated with 1-flouro- 2,4-dinitrobenzene. It gave a DNP-his on the N terminal and free trp when treated with carboxypeptidase. Upon partial hydrolysis of the peptide, the following fragments were obtained. a. his-lle-phe-ala c. his-ala-phe e. ser-lle-his b. ala-phe-trp d. phe-ala-ser Give the amino acid sequence of the above decapeptide.
Question 1 options: The specificity pocket of the serine protease chymotrypsin, which interacts with Tyr and Phe-containing peptide sequences, contains a Ser residue. A research group is trying to modify chymotrypsin such that it has a low KM with Trp-containing peptides. Enter the name or abbreviation of an amino acid that the Ser could be mutated to that would likely have the desired effect. (Hint: look at the diagrams of the specificity pockets shown in the course slides, and consider how the Ser would need to change to account for the difference between Tyr/Phe and Trp.)

OMe NH Ph Nevirapine Atazanavir Staudivine (i) Give the drug target and discuss the anti-HIV mechanism of each of these drugs. Vaccines are an attractive prophylactic treatment against both viral and bacterial diseases. A number of glycaconjugate vaccines using bacterial polysaccharide structures conjugated to protein carriers have been introduced into mass vaccination schemes with excellent results. What differences are there in the immune response to a glycoconjugate vaccine as compared to a polysaccharide vaccine? These glycoconjugate va nes has been used for 30 years without any change in their structures, while the composition of the flu vaccine, based on attenuated or killed virus particies, is changed from year to year. Discuss the reason behind this. (iv) Discuss why it has not been possible to develop a (part structure) vaccine against the HIV virus, based on either I) viral…
