This figure shows the structure of a beta-sheet protein, Z1-Z2 telethonin complex, in the giant muscle protein titin. The inset shows the orientation of the protein backbone of three beta strands (in purple) with hydrogen bonds (yellow) holding the assembly together. Buehler and Keten found that hydrogen bonds in beta-sheet structures break in clusters of three or four, even in the presence of many more bonds. Image / Sinan Keten and Markus Buehler |
