Protein Structure Level Summary Protein structure description • Primary amino acid sequence • Secondary local fold pattern of small subsequence • Tertiary fold of entire protein chain • Quaternary complex of multiple chains Lehninger Princip les of Biochemis try (3rd edition) David L. Nelson, Michael M. Cox Protein Structure Databases. 28 2 Protein Structure. OUTLINE OF TOPICS. The α-Amino Acids. α-Amino acids have an amino group and a carboxyl group attached to a central carbon atom. Amino acids are represented by three-letter and one-letter abbreviations. The Peptide Bond. α-Amino acids are linked by peptide bonds. Folding of proteinsin vivo is promoted by chaperones. Large proteins with a lot of secondary structure may require assisted folding to avoid aggregation of unfolded protein - Molecular chaperones and chaperonins prevent aggregation of unfolded protein. Folding of .

Protein Structure Level Summary Protein structure description • Primary amino acid sequence • Secondary local fold pattern of small subsequence • Tertiary fold of entire protein chain • Quaternary complex of multiple chains Lehninger Princip les of Biochemis try (3rd edition) David L. Nelson, Michael M. Cox Protein Structure Databases. • Chains that are less than amino acids or residues are often referred to as polypeptide chains since they are too smal to form a functional domain. • Larger than this size, they are called proteins • The structure, function and general properties of a protein are all determined by the sequence of amino acids that make up its primary sequence. Folding of proteinsin vivo is promoted by chaperones. Large proteins with a lot of secondary structure may require assisted folding to avoid aggregation of unfolded protein - Molecular chaperones and chaperonins prevent aggregation of unfolded protein.
