Residues controlling the function and stability of the CD corner in myoglobin and hemoglobin
All globins consist of eight $\alpha$ helices labelled A through H and connected by loop regions, except mammalian $\alpha$ globins which lack a D helix. Myoglobin is used as a simple model for the study of the hemoglobin ...
Structure of tropomyosin at 7A resolution
The crystal structure of tropomyosin has been determined by X-ray diffraction analysis at 7A resolution. Tropomyosin is a 400A-long muscle regulatory protein that consists of two parallel 33,000 Dalton alpha helices wound ...
