The beta sheet (β-sheet, also β-pleated sheet) is a common motif of the regular protein secondary structure. Beta sheets consist of beta strands (β-strands)...

and a C-terminus. Many proteins may adopt a beta sheet as part of their secondary structure. In beta sheets, sections of a single polypeptide may run side-by-side...

adjacent to, but not necessarily geometrically aligned with, each other. The beta sheet is anti-parallel, and alternate strands run in the same directions. The...

In protein structures, a beta barrel (β barrel) is a beta sheet (β sheet) composed of tandem repeats that twists and coils to form a closed toroidal structure...

Together the beta-sheets form a funnel-like active site. Each beta-sheet typically has four anti-parallel β-strands arranged in the beta-zigzag motif...

most common secondary structural elements are alpha helices and beta sheets, though beta turns and omega loops occur as well. Secondary structure elements...

adjacent to the diagonal. Antiparallel beta sheets appear in HB plot as cross-diagonal. Parallel beta sheets appears in the HB plot as parallel to the...

(the N-terminus of one sheet is adjacent to the C-terminus of the next), and linked by a short loop of two to five amino acids. Beta hairpins can occur in...

of secondary structure are the structures known as alpha helices and beta sheets that fold rapidly because they are stabilized by intramolecular hydrogen...

secondary and tertiary structure. The PrPsc isoform is more enriched in beta sheets, while the normal PrPc form is enriched in alpha helices. The differences...
