aminosäureabfolge

Aminosäureabfolge refers to the linear sequence of amino acids that make up a protein. This specific order is determined by the genetic code, which is transcribed from DNA into messenger RNA (mRNA) and then translated into a polypeptide chain by ribosomes. Each amino acid is linked to the next by a peptide bond, forming a long chain. The properties and function of a protein are directly dictated by its aminosäureabfolge. Even a single change in this sequence can drastically alter the protein's structure and, consequently, its biological activity, sometimes leading to disease. This sequence is fundamental to understanding protein structure, function, and evolution. Scientists study aminosäureabfolgen to predict protein folding, identify functional domains, and compare proteins across different species. Techniques like protein sequencing and gene sequencing are employed to determine and analyze these crucial sequences. The concept is a cornerstone of molecular biology and biochemistry.
