Illustration of the helix D region of ATIII. A, sequence homology. Sequence homologies of the helix D region of ATIII of different species are shown. Regions critical for heparin binding activity (high and low affinity) and S. aureus V8 protease cleavage sites (arrows) are indicated in the figure. B, schematic representation of ATIII structure (Protein Data Bank code 2B4X). Sequence of the heparin binding peptide FFF21 is indicated.
