Purification and structure of anfibatide with GPIbα. (A) MALDI-TOF mass spectrometry showed a mass to charge ratio (m/z) of 29,799.7. Three-dimensional models of (B) structure of anfibatide (purple) integrated with GPIb (orange) and (C) VWF-A1 domain (green) and GPIbα complex from PDB entry 1SQ045 (https://www.rcsb.org/structure/1SQ0). (D) α-Thrombin (blue) and GPIbα complex from PDB entry 1OOK44 (https://www.rcsb.org/structure/1OOK). Red arrows point to the sulfotyrosine region of GPIbα, the α-thrombin binding site.
