Dictionary of protein secondary structure
WebJul 4, 2024 · Secondary Structure: β-Pleated Sheet. An α-helix is a right-handed coil of amino-acid residues on a polypeptide chain, typically ranging between 4 and 40 residues. This coil is held together by hydrogen bonds between the oxygen of C=O on top coil and the hydrogen of N-H on the bottom coil. Such a hydrogen bond is formed exactly every 4 … WebJul 1, 2003 · The automatic assignment of protein secondary structure from three-dimensional co-ordinates of protein structures is an important and, in principle, a simple bioinformatics tool. Assignments are used to visualise structures, to speed up computationally expensive structural comparisons and to improve sequence searches.

WebThe protein loop, a novel category of nonregular secondary structure, is a segment of contiguous polypeptide chain that traces a "loop-shaped" path in three-dimensional space; the main chain of an idealized loop resembles a Greek omega (ω). A systematic study was made of 67 proteins of known structure revealing 270 omega loops.
