1 One residue, Lys 125, is pivotal for antithrombin to recognize and bind the nonreducing-end trisaccharide of the pentasaccharide in an initial low-affinity complex. Lysine serpin family C member 1 Homo sapiens
2 Two other residues, Lys 114 and Arg 129, then cooperate with Lys 125 to induce the low-affinity complex into an activated, high-affinity complex, in which a network of electrostatic interactions between antithrombin and the entire pentasaccharide is established. Lysine serpin family C member 1 Homo sapiens
