What are the structural and functional differences between the C-terminus and N-terminus of a protein?

Answer 1

The C-terminus and N-terminus of a protein are both important regions that play different roles in the structure and function of the protein. The N-terminus is the end of the protein where the amino acid chain starts, while the C-terminus is where the chain ends. The N-terminus often contains a signal sequence that helps guide the protein to its correct location within the cell, while the C-terminus may be involved in protein-protein interactions or enzymatic activity. Overall, the N-terminus and C-terminus contribute to the overall shape and function of the protein.
