3. The image below depicts 2,3-bisphosphoglycerate depicted in dark gray, and ß subunits are depicted in light gray. (BPG) bound to hemoglobin. The a subunits are BPG (a) Briefly explain how BPG regulates oxygen transport by hemoglobin and describe the critical chemical properties of BPG and its binding pocket.

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.

8. In a patient with anemia, the presence of Heinz bodics in the RBCS was the result of the hemoglobin subunits aggregation due to the oxidation of -SH groups of Hb cysteine residues with active oxygen forms and the formation of disulfide bonds. What metabolic disorders in the RBC can be the cause of this clinical case? To solve the problem: a) indicate which reactions maintain cysteine residues in a reduced state; b) name the coenzyme involved in this process, write a diagram of the process in which the reduced form of this coenzyme is formed; c) indicate the enzyme which deficiency may lcad to a lack of the reduced cocnzyme and be the cause of the clinical case described above.
