Beta-strand is a structural unit of protein beta sheets.This is an extended stretch of polypeptide chain typically 3 to 10 amino acids long that forms hydrogen bonds with other beta-strands in the same beta-sheet. beta-sheet(beta-折叠)是由几个beta-strand(beta-线串)组成的 (beta-strand 没...
beta-sheet是由平行或反平行的beta-strands组成的,含2条或更多beta-strands。箭头指示strand的方向。 laqiwe 2楼: Originally posted by guoliwang at 2014-11-22 00:26:28 每个带箭头的飘带(ribbon)就是一条beta-strand。beta-sheet是由平行或反平行的beta-strands组成的,含2条或更多beta-strands。箭头指示...

Each β−strand is represented by an arrow, which defines its direction starting from the N- to the C-terminus. When the strand arrows point in the same direction, it is a parallel β-sheet (the PDB code for this structure is 2OHX). When the strand arrows point in opposite ...
Firstly, statistical analysis was performed on the sum of beta-strands between each beta-strand pairs in protein sequences. The results showed a propensity of near-neighbor pairing (or called "first come first pair") in the beta-strand pairs. Secondly, based on the same dataset, the pair...
Many secondary prediction methods have been studied, but the prediction accuracy is still unsatisfactory, since beta-sheet prediction is difficult. In this research, we gathered statistics of pairs of three residue sub-sequences in beta-sheets, calculated propensities for them. When a sequence is gi...
β－折叠(β－sheet)也是一种重复性的结构，大致可分为平行式和反平行式两种类型，它们是通过肽链间或肽段间的氢键维系。可以把它们想象为由折叠的条状纸片侧向并排而成，每条纸片可看成是一条肽链，称为β折叠股或β股(β－strand)，肽主链沿纸条形成锯齿状，处于最伸展的构象，氢键主要在股间而不是股内。α...
