Properties of a beta sheet
WebAug 2, 2012 · A large number of studies have been carried out to obtain amino acid propensities for α-helices and β-sheets. The obtained propensities for α-helices are consistent with each other, and the pair-wise correlation coefficient is frequently high. On the other hand, the β-sheet propensities obtained by several studies differed significantly, … WebStrands and sheets (β-strands, parallel and antiparallel β-sheets) β-sheets are a more spacious type of secondary structure formed from β-strands. Strands consist of the protein backbone “zigzagging”, typically for four to ten residues. Single β-strands are not energetically favorable.
