The chapter describes the primary, secondary, tertiary, and the quaternary structure of proteins. The strategy for the determination of the amino acid sequence is based upon the pioneer work of Frederick Sanger, who, in 1953, successfully elucidated the primary structure of the 51-residue ...
5Proteins contain sequences of amino acids joined by peptide links.Amino acid chains (polypeptides) are attracted to each other by hydrogen bonding.5 (a)(i) A section of a protein is formed from one molecule of each of the amino acids glycine(H2NCH2COOH) and alanine (H2NCH(CH3)COOH).Ad...
The bonding mechanisms that hold protein chains together are generally the same as those involved in tertiary structure, with the possible exception that disulfide bonds do not assist in maitaining the quaternary structures of proteins 第四课 氨基酸和蛋白质 蛋白质错综复杂、多种多样的大分子物质,是...

Five amino acids with hydrocarbon side chains decrease in polarity as the length of the side chain is increased. The unique structure of praline (and its hydoxylated derivative, hydroxyproline) causes this amino acid to play a unique role 17、in protein structure.The amino acids with ...
After each protein sequence was represented as a vector of AC variables, a protein pair was characterized by concatenating the vectors of two proteins in this protein pair. Conjoint triad (CT) scores Conjoint triad (CT) considers the properties of one amino acid and its vicinal amino acids and...
Ligand docking to proteins with discrete side-chain flexibility An algorithm is described that explores the conformational degrees of freedom of the amino acid side-chains and of the ligand when docking a putative ligan... Andrew,R.,Leach - 《Journal of Molecular Biology》 被引量: 637发表: ...
