Beta protein sheet

What is the difference between alpha/beta and alpha +beta protein? ... alpha/beta protein are structurally composed of alternating alpha helices and beta sheets in which the beta sheets are mostly ...

The beta pleated sheet is polypeptide chains running along side each other. It is called the pleated sheet because of the wave like appearance. They are linked together by hydrogen bonds. It allows for more hydrogen bonding by stretching out the polypeptide chain. An example of the beta pleated sheet structure is feathers.

Strands of the β sheets are represented as ribbon arrows, pointing in the direction of the C-terminus, and α helices are shown as cylinders. Note the pronounced right-handed twist of the β sheets in these two enzyme structures. Note also the location of the β sheet structures at the core of the proteins. The β-sheet (also β-pleated sheet) is a common motif of regular secondary structure in proteins. Beta sheets consist of beta strands (also β-strand) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.

Some amyloid fibrils can have a β-sheet content of only 35% and an amide I′ maximum at 1617 cm −1 (Fandrich et al. 2003), whereas some proteins have a β-sheet content >50% and an amide I′ maximum at 1643 cm −1 (Table 1 1).
