Section 10- Tertiary Structure Part II

In Section 9, we examined the interactions between elements of secondary structure, and then reviewed supersecondary structure.

We now progress to domains and their folds. A single protein may consist of several or many domains, but many proteins are single-domain.

Proteins with many (often repeated) domains are termed mosaic proteins.

Multi-domain proteins can have domains of very different types. Three major classes are globular (water-soluble), membrane-bound ('lipid soluble') and fibrous. On this basis, whole proteins can also be classified into different types.
