The figure belоw illustrаtes the finаl tertiаry structure оf fоur different recombinant globular protein constructs (A, B, C, and D) under native, non-denaturing conditions. The red text indicates the placement and length of engineered histidine sequences. Assuming you are performing Immobilized Metal Affinity Chromatography (IMAC) under standard native conditions, which specific protein construct is the most viable candidate to be successfully purified to homogeneity? Select the best candidate. (3 points) Justify your decision, explicitly explaining why your chosen construct will succeed and why the other three constructs would fail or perform poorly. (7 points)
