You have discovered a novel protein that has a pl = 5.5. To study the functional properties of this new protein your research group has made a mutant that contains two amino acid changes-namely, a surface Phe residue in the normal protein has been replace by His (side chain pk, = 6.1), and a surface Gln has been replace by Glu (side chain pk = 6.0). The pl of the %3D mutant protein is predicted to be: A. Greater than the pl of the normal protein.

Can you check if A is correct and please help answer the following questions?
The amide hydrogen atoms of peptide bonds within proteins can exchange with protons in the solvent. In general, amide hydrogen atoms in buried regions of proteins and protein complexes exchange more slowly than those on the solvent-accessible surface do. Determination of these rates can be used to explore the proteinfolding reaction, probe the tertiary structure of proteins, and identify the regions of protein–protein interfaces. These exchange reactions can be followed by studying the behavior of the protein in solvent that has been labeled with deuterium ( ²H), a stable isotope of hydrogen. What two methods described in this chapter could be readily applied to the study of hydrogen– deuterium exchange rates in proteins?
In a-c below, will the residue on the right-hand side increase or decrease the pKa of the residue on the left-hand side? Explain.
Based on this alignment, you can identify areas of the protein sequences that are key regions of the proteins. If you were to design a targeted mutagenesis programme to try to disrupt the activity of the proteins in this current alignment as part of a research programme, which THREE amino acid sequence regions (motifs) would you target? List your sequence motifs in order of preference (number 1 being your most confident target). Explain your reasoning for each motif

Given the following diagram of how protein AWESOME1 binds to it's target DNA, describe the potential effects of each of the 5 mutations shown below. The wild-type sequence of a helix #1 is also shown in the blue box, and all the mutations are in helix #1 (see numbers for identifying particular residues). a helix #1 R(1)-V-I-L-Y-F-W-I-M-Y-F-S-H-Y-W-R(16) #1 Predict the consequence of the following mutations: 1) Arg(1) to Glu 2) Arg(1) to Ala 3) Phe(6) to lle 4) Trp(7) to Phe 5) Met(9) to Pro in
