From Psophocarpus tetragonolobus

Other associations have been investigated by the same methods. Lectin UE-I from Ulex europaeus (Section 15.4.3) and PT-II from Psophocarpus tetragonolobus both bind the H-type trisaccharide glycoside a-L-Fuc-(l—>2)-j3-D-Gal-(1—>4)-)3- D-GlcNAc-(l-OMe). With the Ulex lectin, the thermodynamic parameters are A/r "-29, TAS -20.5 kcal mol" . Again a decrease in entropy is observed. However, with the Psophocarpus lectin, the figures are ATT "- 5.4, TA5° -I- 0.8 kcal mol" . In the latter case, the small increase in entropy seems to indicate an important hydrophobic effect.
