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 …

Metal-ligand interactions are inherent in a succession of important self-assembly strategies
used in supramolecular chemistry. To this extent, the development of chelating ligands and …

Geometrical validation around the C is described, with a new C measure and updated
Ramachandran plot. Deviation of the observed C atom from ideal position provides a single …

Cytochromes c are haemoproteins which carry out electron transfer in a wide variety of
biological systems, necessitating different kinds of cytochrome c to fulfill different biological …

Abstract Background The Ramachandran plot is a fundamental tool in the analysis of protein
structures. Of the 4 basic types of Ramachandran plots, the interactions that determine the …

The object of this article is to review the developments in the field of intramolecularly H-
bonded extended and folded conformations in linear and cyclic peptide molecules. The …

In recent years, the utilization of terpyridines both in macromolecular structure assembly and
device chemistry has exploded, enabling, for example, supramolecular polymer …

Two different, theoretical studies of intramolecular proton-proton distances in polypeptide
chains are described. Firstly, the distances between amide, C α and C β protons of …

The alanine dipeptide1 (see Figure 1) has served as a paradigm for theoretical studies of
backbone conformationalequilibria in proteins. This is because the dipeptide contains many …

Although many globular proteins have a well-defined equilibrium geometry in the native
state, their flexibility and structural fluctuations play an important role in their activity …
