Proteins spontaneously self-organize into specific, folded structures determined by their amino acid sequences and the interaction between molecular forces. Since the 3-dimensional structure into which they fold often relates to the specific function of the protein, much effort has been directed towards...
Studying the secondary structure of proteins leads to an understanding of the components that make up a whole protein, and such an understanding of the structure of the whole protein is often vital to understanding its digestive behaviour and nutritive value in animals. The main protein secondary ...
This section provides a quick introduction of protein secondary structures, alpha helix and beta sheet. Both structures are stabilized by hydrogen bonds between oxygen atoms and hydrogen atoms of two amino acid residues lined up side by side.

A database of 528 β-proteins and β-domains containing abcd units, including 244 nonhomologous ones, was compiled from the Protein Data Bank (total 1511 PDB entries). A novel structural tree of this class of proteins was constructed to include 153 possible polypeptide chain folds. A structural...

Alpha (α) keratins are found in all vertebrates, while beta (β) keratins are found exclusively in reptiles and birds. We have studied the molecular evolution of these gene families in the genomes of 48 phylogenetically diverse birds and their expression in the scales and feathers of the ...
Studies on individual proteins, groups of ancient proteins and genome-wide surveys of alpha helices and beta strands indicated gene-structure and protein-structure correlation (=-=Barik, 2004-=-; de Souza et al., 1996; Holmes and Parham, 1985). Intron phase match studies suggested that domains...
