Proteins and Enzymes

ID #2334

I am totally lost on the one of the slides in lecture 5 that illustrates hydrophobic clusters in a quaternary structure. What are hydrophobic clusters (other than they "hide" from water) and how do they get to where they are in the figure?

In an aqueous environment (like the cytoplasm), a quaternary structure's hydrophobic interactions cluster together away from the water. In the case of multiple polypeptide chains, this can be on the inside of an individual polypeptide chain or between multiple polypeptide chains, but not towards the outside of the protein. The hydrophobic side chains aren't necessarily attracted to each other, but they have the same "goal," and that is to get away from water. Because of this, they often end up clustered together. It's that simple, there isn't any more to it!
