Cover Story: Fibrinogen is central to a myriad of clotting diseases and disorders including stroke. This article reports the discovery in the venoms of many varanid lizards novel enzymes which selectively cleave the different chains of fibrinogen to produce anticoagulant states. Such selective cleavage in snake venom enzumes, such as Ancrod/Arvin, has led to their therapeutic use. The unique forms discovered in lizard venoms thus have drug design and development potential.
