What are the differences between the structures and functions of the c-terminus and n-terminus of a protein?

Answer 1

The c-terminus and n-terminus of a protein are two distinct regions. The n-terminus is the starting point of a protein chain, while the c-terminus is the end point. Functionally, the n-terminus often plays a role in targeting the protein to specific locations within the cell, while the c-terminus can be involved in protein-protein interactions and signaling pathways. Structurally, the n-terminus tends to be more flexible and exposed, while the c-terminus is often more rigid and buried within the protein's structure.
