Active residues are exposed to water and interact with the ligand. Passive residues are also in contact with water and are situated proximate to the active ones.<ref> Roterman-Konieczna, Irena.

<scene name='56/568023/Passive_residues_binding/2'>Three amino acids</scene> at the FRB domain contribute passively to the binding of the activator (L2031, S2035, W2101). The positive charged arginine residue '''R2109''' plays a key role in the binding of phosphatidic acid as it binds to the negetively charged phosphate group. | <scene name='56/568023/Passive_residues_binding/2'>Three amino acids</scene> at the FRB domain contribute passively to the binding of the activator (L2031, S2035, W2101).
