Protein A has a binding site for ligand X with a Kd of 10-6 µM. Protein B has a binding site for ligand X with a Kd of 10-9 µM. Which statement is incorrect?

#Unit 1. Molecules and their Interaction Relevant to Biology
  1. Protein B has a higher affinity for ligand X.
  2. Protein A has a lower affinity for ligand X.
  3. At 10-9 µM conc of X, protein A will be 99% saturated
  4. At 10-9 µM conc of X, protein B will be 50% saturated
