2. The diagram to the right shows the change in the structure of the C-terminal portion of each of the ẞ-subu- nits of human hemoglobin (HbA) in the oxyHb to deox- yHb or R-to-T transition. The hydrogen bonding interac- tion of the C-terminal ẞHis 146 residue with the side chain of Asp94, highlighted by the red ellipse, has been shown to be responsible for a major portion of the proton uptake associated with the Bohr effect. Treatment of HbA with the enzyme carboxypeptidase A (CPA) results in loss of the C-terminal ẞHis 146 and ẞTyr145 residues of the ẞ- subunits. (a) ( ) Draw a Hill plot [log(Y/[1-Y]) vs. log(pO2), Y = fraction of heme groups occupied by O2] to compare the values of the Hill coefficient nн and the O2-binding affinity at pH 7.4 of normal HbA before and after treat- ment of with CPA.

3. The trp repressor is a homodimer with 107 amino acid residues per monomer. The content of proton dissociable groups of each monomer is given below: Side chain pKa number/monomer ZpH 4 ZpH 6 12.5 Arginine Aspartate Glutamate 9. 4.0 4.0 10 Histidine 6.0 2 Lysine Tyrosine -NH3® 10.0 6 9.5 2 7.0 1 -СООН 4.0 1 (a) ( : ) The isoelectric point (pl) of the protein, i.e., the pH at which the overall electrostatic charge on the protein E z = 0, is 5.3.

5-Bromouracil is an analogue of thymine that usually pairswith adenine. However, 5-bromouracil frequently pairs withguanine. Explain.
3. Draw both hemiacetal forms of d-ribofuranose and both hemiacetal forms of d-xylofuranose.
The following amino acids that are often found inside globulin molecules are () A, Tyr B, Phe C, Asn D, Glu True of false 1. In the de novo synthesis of purine nucleotides and pyrimidine nucleotides, base rings are first synthesized and then corresponding nucleotides are formed with phosphoribose. () 2. Transcription is the process of transferring genetic information from DNA to RNA. DNA is synthesized under the catalysis of RNA polymerase, and the direction of synthesis is from the 5 'end to the 3' end. () 3. The change of protein conformation is caused by the breaking of covalent bonds within the molecule. () 4. In very high and very low pH solutions, amino acids exist mainly in non-ionic form. () 5. The active center of an enzyme usually consists of several amino acid residues adjacent to each other in the primary structure. ()
9. The T conformation of the hemoglobin tetramer is stabilized (in part) by a salt linkage between the side chain of the lysine residue at position 40 in the a-chain of one aß dimer and the C-terminal carboxylate group of the ß-chain of the opposing aß dimer. Draw a diagram of this salt linkage (show complete side chains).

In Figure 1-8b, can you tell if the number of hydrogenbonds between adenine and thymine is the same as thatbetween cytosine and guanine? Do you think that aDNA molecule with a high content of A + T would bemore stable than one with high content of G + C?
