Binding of arachidonic acid (AA), thromboxane A2 (TXA2) and carbocyclic TXA2 (cTXA2) by moubatin, TSGP2 and TSGP3 as measured by microcalorimetry. In each case, protein (2µM) was titrated against 20µM ligand. Indicated are thermodynamic parameters derived for each titration that includes the stoichiometry of binding (N), dissociation constant (KD), change in enthalpy (ΔH) and change in entropy (TΔS) upon binding. Also shown are the structures of arachidonic acid, U46619 and cTXA2.
