Abstract: | Agkisacucetin is a snake C‐type lectin isolated from the venom of Agkistrodon acutus (A. acutus). It binds specifically to the platelet glycoprotein (GP) Ib and prevents the von Willebrand factor (VWF) accessing it. We determined the crystal structure of agkisacucetin to 1.9Å resolution. The structure of agkisacucetin has an (αβ) fold similar to another GPIb‐binding protein, flavocetin‐A, but lacks the C‐terminal cysteine in the β‐subunit, does not form (βα)4 tetramers, and does not cluster GPIbs, like flavocetin‐A.
