Polyproline-II helix in proteins: structure and function
The poly-l-proline type II (PPII) helix in recent years has emerged clearly as a structural class
not only of fibrillar proteins (in collagen, PPII is a dominant conformation) but also of the …

A fresh look at the Ramachandran plot and the occurrence of standard structures in proteins
SA Hollingsworth, PA Karplus - 2010 - degruyter.com
The Ramachandran plot is among the most central concepts in structural biology, seen in
publications and textbooks alike. However, with the increasing numbers of known protein …

Left-handed polyproline II helices commonly occur in globular proteins
The main-chain conformations of 80 proteins were analyzed to identify helical structures that
commonly occur but do not fall into the known classes of α-helix, 3 10-helix and β-sheet. The …

Statistical clustering techniques for the analysis of long molecular dynamics trajectories: analysis of 2.2-ns trajectories of YPGDV
The microscopic interactions and mechanisms leading to nascent protein folding events are
generally unknown. While such short time-scale events are difficult to study experimentally …

Evolutionary analysis of polyproline motifs in Escherichia coli reveals their regulatory role in translation
Translation of consecutive prolines causes ribosome stalling, which is alleviated but cannot
be fully compensated by the elongation factor P. However, the presence of polyproline …

Structure of coiled β‐β‐hairpins and β‐β‐corners
AV Efimov - FEBS letters, 1991 - Wiley Online Library
Two types of super‐secondary structure, coiled β‐β‐hairpins and β‐β‐corners, are
considered in this paper. A β‐β‐corner can be represented as a long β‐β‐hairpin folded …
