FXa interface amino acid residues. A. Amino acid residues of the heavy chain of FXa at the interface of the selected docked complexes for each SVPLA2. The sequence of FXa shows only residues detected in the X-ray experiment. The last line shows the experimentally reported residues of FXa involved in the binding to FVa [2, 78, 79, 83]. We use Renetseder's notation for the SVPLA2s and chymotrypsinogen notation for FXa. The sequences of CBc, AtxA, CbII and CBa2 were aligned with respect to MtxII. B. Amino acid residues of the light chain of FXa at the interface of the selected docked complexes for each SVPLA2.
