The N terminal, or N-terminus, of a protein is the end characterized by a free amino group. This is because proteins are made up of amino acids, which have a free amino group at one end and a free carboxyl group at the other end. The N-terminus is usually the first amino acid in the protein sequence and is important for the overall structure and function of the protein.
