Vanin 1 is a key protein that is involved in the breakdown of pantetheine to panthothenic acid and cysteamine. These proteins are associated with many metabolic diseases like type 2 diabetes. Understanding the binding interaction would give insight into treating these diseases more effectively. Vanin 1 has three catalytic residues (Glu79, Lys178 and Cys211) that represents the active site of the enzyme.The active site is located in the center of the enzyme in between the two sub-units. It was discovered that Glu79 and Lys178 were responsible for orienting and activating Cys211 to catalyze the reaction. The substrate forms a covalent bond with Cys211 producing the transition state.
