Two proteins, X and Y, bind to the same ligand, A, with the binding curves shown below. Which of the statement is correct for the graph analysing two proteins?

#Unit 1. Structure and Function of Biomolecules

  1. For X, Kd is 1 micromole; for Y, Kd is 2 micromole & Because Y is half-saturated at a lower [B], it has a higher affinity for the ligand.

  2. For X, Kd is 3 micromole; for Y, Kd is 6 micromole & Because X is half-saturated at a lower [B], it has a higher affinity for the ligand.

  3. For X, Kd is 6 micromole; for Y, Kd is 2 micromole & Because Y is half-saturated at a lower [A], it has a higher affinity for the ligand.

  4. For X, Kd is 2 micromoles; for Y, Kd is 6 micromole & Because X is half-saturated at a lower [A], it has a higher affinity for the ligand.
