Chapter 29: Q26. (page 1183)

Consider two molecules of a tetrapeptide composed of only alanine residues. Draw the hydrogen bonding interactions that result when these two peptides adopt a parallel 尾-pleated sheet arrangement. Answer this same question for the antiparallel 尾-pleated sheet arrangement.

Short Answer

Expert verified

parallel 尾-pleated sheet

antiparallel 尾-pleated sheet

Step by step solution

01

 Parallel -pleated sheet

In a parallel -pleated sheet, the strands run in the same direction from the N- to C-terminal amino acid. The given tetrapeptide is composed of alanine

parallel 尾-pleated sheet

The dotted lines represent the intermolecular hydrogen bonding.

02

Antiparallel -pleated sheet

In an antiparallel -pleated sheet, the strands run opposite.

antiparallel 尾-pleated sheet

The dotted lines represent the intermolecular hydrogen bonding.
