Effects of cutting the substrate, APS and the product, AMP into fragments on ligand Kd values. The energetic effect that results from connectivity was calculated based on the affinity of the parent ligand ‘XY’, compared with the affinities of its pieces, ‘X’ and ‘Y’: ΔGconn = −RTln(KXY/KXKY), as previously reported23.
