Beta turns are the most common type of secondary structure in proteins after alpha helices and beta sheets and play many key structural and functional roles. Turn backbone (BB) geometry has been classified at multiple levels of precision, but the current picture of side chain (SC) structure ...
The number of beta-turns in a representative set of 426 protein three-dimensional crystal structures selected from the recent Protein Data Bank has nearly doubled and the number of gamma-turns in a representative set of 320 proteins has increased over seven times since the previous analysis. Bet...

Focuses on the applicability of 2-amino-3-oxohexahydroindolizino[8,7-b]indole-5-carboxylate system (IBTM) as a dipeptide surrogate of type II' beta-turn mimetic. Classification of IBTM; Surface localization of turns in proteins; Conformational properties of type II' beta-turns; Use of ...
β-Turns have been extracted from 59 non-identical proteins (resolution 2 ) using the standard criterion that the distance between C α( i) and C α( i + 3) is less than 7 (1 = 0·1 nm). The β-turns have been classified, using φ, ψ angles, into seven conventional turn types...
An automated computer prediction of the chain reversal regions of globular proteins is described herein using bend frequencies and beta-turn conformational parameters (Pt) determined from 408 beta-turns in 29 proteins calculated from x-ray atomic coordinates. The probability of bend occurrence at residu...

A secondary structure that occurs in many proteins and consists of two or more parallel adjacent polypeptide chains arranged in such a way that hydrogen bonds can form between the chains. Also called beta pleated sheet, pleated sheet.[From beta-form, the form taken by a protein molecule after...
