1. Ac1-Proteinase from the venom of Agkistrodon acutus was isolated in a homogeneous form by a previously published method. 2. Ac1-Proteinase possessed lethal, hemorrhagic, caseinolytic, azocaseinolytic, azoalbumin hydrolytic and hide powder azure hydrolytic activities. 3. The toxin also hydrolyzed the oxidized B chain of insulin and fibrinogen. The cleavage sites in the oxidized B chain of insulin were identified as Ala(14)-Leu(15) and Tyr(16)-Leu(17). The A alpha chain of fibrinogen was digested. 4. Biological properties of Ac1-Proteinase were investigated further and are reported in this paper.
