And we reformed the proper secondary and tertiary structure of that particular enzyme. So initially, we place this native enzyme with access Beter mechatoethanol and ate molar urea. And what happens is our enzyme is denatured. But when the denaturing agents were removed via the process of dialysis by using a semipermeable membrane, the enzyme eventually reformed its original tertiary structure. Now, what this basically shows is it gives us evidence that it's the primary sequence, it's the primary structure, it's that specific sequence of amino acids that essentially dictates the proper formation of the tertiary structure of that enzyme. Now let's move on to experiment two and see what experiment two was.
