Interaction of Heparin with Annexin V, I. Capila, V. A. VanderNoot,T. R. Mealy, B. A. Seaton, RJ. Linhardt, FEBS Letters, 446,327-330, 1999.
The energetics and kinetics of the interaction of heparin with the Ca2+ and phospholipid binding protein annexin V, was examined and the minimum oligosaccharide sequence within heparin that binds annexin V was identified. Affinity chromatography studies confirmed the Ca2+ dependence of this binding interaction. Analysis of the data obtained from surface plasmon resonance afforded a Kd of approximately 21 nM for the interaction of annexin V with end-chain immobilized heparin and a Kd of approximately 49 nM for the interaction with end-chain immobilized heparan sulfate. Isothermal titration calorimetry showed the minimum annexin V binding oligosaccharide sequence within heparin corresponds to an octasaccharide sequence. The Kd of a heparin octasaccharide binding to annexin V was approximately 1 microM with a binding stoichiometry of 1:1.;
