What are the differences between the C-terminus and N-terminus of a protein in terms of their functions and structural significance?

Answer 1

The C-terminus and N-terminus of a protein are the two ends of the protein chain. The N-terminus is where the protein chain starts, while the C-terminus is where it ends.

In terms of functions, the N-terminus often plays a role in targeting the protein to specific locations within the cell or in interactions with other molecules. The C-terminus, on the other hand, can be involved in signaling for protein degradation or in binding to other proteins.

Structurally, the N-terminus and C-terminus can affect the overall shape and stability of the protein. The N-terminus may contain signal sequences that help guide the folding of the protein, while the C-terminus can influence how the protein interacts with other molecules.

Overall, the N-terminus and C-terminus of a protein play important roles in its function and structure, with each end contributing unique characteristics to the protein's overall behavior.
