Consider a protein domain consisting of 98 amino acid residues and arranged as a β−sheet made of 9 β−strands connected through β−turns. what is the area of the β−sheet. round your result to the nearest one. additional information and hints: a β−turn contains four amino acid residues the width of a β-strand, including half of the distance between it and the next strand is 4.2 å. the distance between two amino acid residues within a β−strand is 3.3 å. hint 1. to determine the width of the β−sheet you would need to determine the number of strands. hint 2. to determine the length of the β−sheet, you need to find out the number of amino-acid residues in each β−strand. the following is just an example of a sheet consisting of 3 strands of 11-residue long each.
