Protein Structure

Encompassing all aspects of the structures of peptides and proteins, this book adopts a uniquely problem-oriented approach to the topic. Starting with a look at the structures and properties of the twenty amino acids that occur in proteins, and moving on to the synthesis of polypeptides and the isolation of proteins, Peptides and Proteins then addresses the methods of analysis of protein characteristics, including the modern methods of sequence analysis by mass spectrometry. Further chapters examine the three-dimensional nature of protein structure, and introduce the student to the use of computer applications (molecular graphics, databases, bioinformatics) in protein chemistry. Original research data is used in many of the problems, and throughout sufficient background biology is included, thus putting the subject into context for chemists. Aimed at first and second-year chemistry students, this title will also be of interest to students of biochemistry.

"From the Foreword "[A] must read for all of us committed to understanding the interplay of structure and function...[T]he individual chapters outline the suite of major basic life science questions such as the status of efforts to predict protein structure and how proteins carry out cellular functions, and also the applied life science questions such as how structural bioinformatics can improve health care through accelerating drug discovery."" This book provides a basic understanding of the theories, associated algorithms, resources, and tools used in structural bioinformatics. The reader emerges with the ability to make effective use of protein, DNA, RNA, carbohydrate, and complex structures to better understand biological function. Moreover, it draws a clear connection between structural studies and the rational design of new therapies.

Protein structure prediction - Protein structure prediction is one of the most significant technologies pursued by computational structural biology and theoretical chemistry. It has the aim of determining the three-dimensional structure of proteins from their amino acid sequences.

Protein structure - Proteins are amino acid chains, made up from 20 different L-Î±-amino acids, also referred to as residues, that fold into unique three-dimensional protein structures. The shape into a which a protein naturally folds is known as its native state, which is determined by its sequence of amino acids.

Supersecondary structure - In 1976 only 56 protein structures were available in the PDB cite(bernstein1977), yet tertiary structure had already been generally classified into four secondary structure classes cite(levitt1976) and three different 'folding units' or supersecondary structures cite(lesk2001), speculated to be the 'building blocks' of tertiary structure cite(levitt1976,chothia1977). The prevalence of common secondary and supersecondary structures in proteins is explained by the thermodynamic stability conferred by these protein conformations cite(chothia1984,finkelstein1987).

Protein sequencing - Proteins are found in every cell and are essential to every biological process, protein structure is very complex: determining a protein's structure involves first protein sequencing - determining the amino acid sequences of its constituent peptides; and also determining what conformation it adopts and whether it is complexed with any non-peptide molecules. Discovering the structures and functions of proteins in living organisms is an important tool for understanding cellular processes, and allows drugs that target specific metabolic pathways to be ...

Molecule Structure - Molecule Structure Primary structure - In biochemistry, the primary structure of an unbranched biopolymer, such as a molecule of DNA, RNA or protein, is the specific nucleotide or peptide sequence from the beginning to the end of the molecule. The primary structure, in other words, identifies a biopolymer's exact chemical composition and the sequence of its monomeric subunits. Quaternery structure - The 'Quarternary structure' is the fourth chapter of looking into the structure of the molecule, for example, the quarternary structure of ...

Protein Molecule - Protein Molecule Protein subunit - In structural biology, a protein subunit or subunit protein is a single protein molecule that assembles (or "coassembles") with other protein molecules to form a multimeric or oligomeric protein. Many naturally-occurring proteins and enzymes are multimeric. Protein ligands - In biochemistry, a protein ligand is an atom, a molecule or an ion which can bind to a specific site (the binding site) on a protein. Interactions between any protein and its ligands are fundamental and essential for ...

Plasma Protein - Plasma Protein C-reactive protein - C-reactive protein (CRP) is a plasma protein, an acute phase protein produced by the liver. It is a member of the pentraxin family of proteins. Integral membrane protein - An Integral Membrane Protein (IMP) is a protein molecule (or assembly of proteins) that in most cases spans the biological membrane with which it is associated (especially the plasma membrane) or which, in any case, is sufficiently embedded in the membrane to remain with it during the ...

Function of Plasma Protein - Function of Plasma Protein Bence Jones protein - A Bence Jones protein is a protein often found in the blood and urine of patients with multiple myeloma. The proteins are immunoglobulin free light chains (paraproteins) and are produced by defective plasma cell function. Scaffold protein - A scaffold protein is a protein whose function is to promote other protein-protein interactions. Protein ligands - In biochemistry, a protein ligand is an atom, a molecule or an ion which can bind to a specific site ( ...
