Publisher Summary This chapter investigates the anatomy and taxonomy of protein
structures. A protein is a polypeptide chain made up of amino acid residues linked together …

Proteases or proteolytic enzymes form one of the largest and more important groups of
enzymes. Proteases selectively catalyze the hydrolysis of peptide bonds and can be divided …

The crystal structure of human erythrocytic ubiquitin has been refined at 1.8 Åresolution
using a restrained least-squares procedure. The crystallographic R-factor for the final model …

Peter Y. Chou and Gerald D. Pasman* abstract: The helix,/3-sheet, and coil conformational
param-eters, Pa, Pp, and Pc, for the 20 naturally occurring amino acids have been computed …

This volume of" Water-A Comprehensive Treatise" is devoted to aqueous solutions of
macromolecules and aqueous systems of small molecules which exhibit reversible …

This report is one of a series of papers that introduce and use a new and highly simplified
treatment of protein conformations. The first paper (Levitt & Warshel, 1975) outlined the …

A simple diagrammatic representation has been used to show the arrangement of α helices
and β sheets in 31 globular proteins, which are classified into four clearly separated classes …

A method of comparing the conformations of different, but structurally related proteins is
described. Local variations, such as the systematic translation of a helix, or the position of …

The accessible surface areas have been calculated for the individual residues in 12
proteins, and for the extended chains, the secondary structures and tertiary structure of six …

The thermal properties of five globular proteins with known spatial structure, ribonuclease,
lysozyme, chymotrypsin, cytochrome c and myoglobin, are investigated by scanning …
