Figure 6 Superposition of the bovine trypsin (V) and human factor Xa DX-9065a (PDB entry 1fax) complexes. The C atoms of the inhibitor (V) and DX-9065a are colored green and blue, respectively. The majority of the C atoms in trypsin are colored gray and in factor Xa are colored black. C atoms of the five amino-acid changes between bovine trypsin and human factor Xa (Asn/Asp97, Tyr/Leu99, Gln175/Phe174, Ser/Ala190 and Ser/Glu217) have been colored green in trypsin and purple in human factor Xa. The catalytic triad residues (Ser195, His57 and Asp102) in both structures are colored orange.
