Carbohydrates can play important roles by modulating interactions between proteins. For example, Figure 7-27 (7th ed) shows how heparin (repeating unit of glycosaminoglycan, see Figure 7-22) binding can modulate the interaction between thrombin and anti- thrombin. What role do the sulfates of heparin play in stabilizing this complex, and what is the consequence of that stabilization? Select one: O a. The sulfates bind to pockets on both proteins lined with glutamate and aspartate residues. The binding of heparin and the stabilization of the thrombin-anti-thrombin complex activates the protease (thrombin), initiating the coagulation cascade. b. The sulfates bind to pockets on both proteins lined with glutamate and aspartate residues. The binding of heparin and the stabilization of the thrombin-anti-thrombin complex keeps the protease (thrombin) from initiating the coagulation cascade. O c. The sulfates bind to pockets on both proteins lined with arginine and lysine residues. The binding of heparin and the stabilization of the thrombin-anti-thrombin complex activates the protease (thrombin), initiating the coagulation cascade. O d. The sulfates bind to pockets on both proteins lined with glycine and proline residues. The binding of heparin and the stabilization of the thrombin-anti-thrombin complex activates the protease (thrombin), initiating the coagulation cascade.
