Three-Dimensional Structures and Mechanisms of Snake Venom Serine Proteinases, Metalloproteinases, and Phospholipase A(2)s

High-resolution crystal structures provide accurate information of the positions of the atoms which can be used to understand substrate specificity, secondary binding sites, and catalytic mechanisms. Detailed structural information and mechanisms of serine proteinases, metalloproteinases, and phospholipases A(2)s are presented.
