The<unk>  (also known as the amino-terminus, NH2-terminus, N-terminal end or amine-terminus) refers to the end of a protein or polypeptide terminated by an amino acid with a free amine group (-NH2). The convention for writing peptide sequences is to put the<unk>  on the left and write the sequence from N- to<unk> . When the protein is translated from messenger RNA, it is created from<unk>  to<unk> .
