Sickle-Cell anemia is caused by a point mutation in the B-globin chain of hemoglobin. This causes the hydrophilic amino acid, glutamic acid, to be replaced with the hydrophobic amino acid, valine at the sixth position. This causes a change in the protein's folding.
In adults hemoglobin normally consists of four protein subunits: two subunits of beta-globin and two subunits of a protein called alpha-globin, which is produced from another gene called HBA. Each of these protein subunits is attached to an iron-containing molecule called heme. Each heme contains an iron molecule in its center that can bind to one oxygen molecule.
Explain the effect this single mutation has on protein folding and how this leads to the diseases state of Sickle Cell anemia.
