Rotamer libraries are widely used in protein structure prediction, protein design, and
structure refinement. As the size of the structure data base has increased rapidly in recent …

The accurate determination of a large number of protein structures by X-ray crystallography
makes it possible to conduct a reliable statistical analysis of the distribution of the main …

An analysis of a non-redundant set of protein structures from the Brookhaven Protein Data
Bank has been carried out to find out the residue preference, local conformation, hydrogen …

On the occasion of their fiftieth birthday, it is opportune to review the first half century of
Ramachandran plots. In the present review, some of the most relevant aspects of this fifty …

A total of 19 835 polar residues from a data set of 250 non-homologous and highly resolved
protein crystal structures were used to identify side-chain main-chain (SC-MC) hydrogen …

Designed octapeptide β-hairpins containing a central DPro-Gly segment have been used as
a scaffold to place the aromatic residues Tyr and Trp at various positions on the antiparallel …

An analysis of the occurrence of nonglycyl residues in conformations disallowed in the
Ramachandran plot is presented. Ser, Asn, Thr, and Cys have the highest propensities to …

In this work, we expand on a dataset recently introduced for protein interface prediction
(PIP), the Database of Interacting Protein Structures (DIPS), to present DIPS-Plus, an …

Turns are irregular secondary structure elements with a hydrogen bond or a specific Cα‐Cα
distance between the first and the last residue. They are up to six residues in length. Here …

Statistical analysis of coil regions in protein structures has been used to obtain the local
backbone ϕ, ψ preferences of amino acids, which agree well with the NMR experiments of …
