Purification and enzymatic characterization of a novel metalloprotease from Lachesis muta rhombeata snake venom
Abstract Background Lachesis muta rhombeata (Lmr) is the largest venomous snake in Latin America and its venom contains mainly enzymatic components, such as serine and metalloproteases, L-amino acid oxidase and phospholipases A2. Metalloproteases comprise a large group of zinc-dependent proteases th...
