It is a 23 kDa protein consisting of a single compact L-shaped domain, composed of seven alpha-helices that run antiparallel to each other. 70% of the amino acids are in alpha-helix conformation and no beta-sheet is present.... |
https://en.wikipedia.org/wiki/Brazier%20effect | The Brazier effect was first discovered in 1927 by Brazier. He showed that when an initially straight tube was bent uniformly, the longitudinal tension and compression which resist the applied bending moment also tend to flatten or ovalise the cross-section. As the curvature increases, the flexural stiffness decreases.... |
