trimer RVV-X is a heterotrimeric metalloproteinase with a mammalian ADAM-like heavy chain and two lectin-like light chains, it shows a hook-spanner-wrench-like architecture, in which the metalloproteinase/disintegrin region constitutes a hook, and the lectin-like domains constitute a handle Daboia russelii
